There we discussed about Remainder Theorem, Factor Theorem and explained the Method of factoring with Example.

Here, we will apply the method to solve problems. The knowledge of Synthetic Division is made use of here. That knowledge is a prerequisite here. So, please learn the method before proceeding further.

Let f(x) = x^{4} + 5x^{3} + 5x^{2} - 5x - 6 Here constant term = -6. Its factors are +1,-1,+2, -2, +3, -3, +6, -6. So we check witha = +1,-1,+2, -2, +3, -3, +6, -6 whether f(a) is zero or not. f(1) = 1 + 5 + 5 - 5 - 6 = 0 ⇒ x -(1) = (x - 1) is a factor of f(x). Now let us divide f(x) = (x^{4} + 5x^{3} + 5x^{2} - 5x - 6 ) by (x - 1) usingSynthetic Division (For detailed explanation of Synthetic Division see Example 1 above.)

Let p(x) = x^{3} + 6x^{2} + 11x + 6This is a third Degree Polynomial, which is to be factorized using Facor Theorem. Here constant term = 6. Its factors are +1,-1,+2, -2, +3, -3, +6, -6. So we check witha = +1,-1,+2, -2, +3, -3, +6, -6 whether f(a) is zero or not. p(1) is obviously not zero, as all the coefficients are positive. p(-1) = (-1)^{3} + 6(-1)^{2} + 11(-1) + 6 = -1 + 6 -11 +6 = 0 ⇒ x -(-1) = (x + 1) is a factor of p(x). Now let us divide p(x) = (x^{3} + 6x^{2} + 11x + 6) by (x + 1) usingSynthetic Division (For detailed explanation of Synthetic Division see Example 1 above.)

∴ Quotient = (+1)x^{2} + (+5)x + (6) = x^{2} + 5x + 6 Thus, p(x) ÷ (x + 1) = x^{2} + 5x + 6 ∴ p(x) = (x + 1)(x^{2} + 5x + 6) We can factorize x^{2} + 5x + 6 using the knowledge of factoring Polynomials of second degree. x^{2} + 5x + 6 = x^{2} + 2x + 3x + 6= x(x + 2) + 3(x + 2) = (x + 2)(x + 3) ∴ p(x) = (x + 1)(x + 2)(x + 3) ∴ f(x) = (x - 1)p(x) = (x - 1)(x + 1)(x + 2)(x + 3). Thus, x^{4} + 5x^{3} + 5x^{2} - 5x - 6 = (x - 1)(x + 1)(x + 2)(x + 3). Thus Factoring Polynomial x^{4} + 5x^{3} + 5x^{2} - 5x - 6 by using Factor Theorem gave the Factors as(x - 1)(x + 1)(x + 2)(x + 3). Ans. Thus, the problem on Math Factoring is solved.

Example 2 of Math Factoring

Solve the following problem on Math Factoring

Factorize 4x^{4} - 12x^{3} + 7x^{2} + 3x - 2

Solution to Example 2 of Math Factoring :

Let f(x) = 4x^{4} - 12x^{3} + 7x^{2} + 3x - 2 Here constant term = -2. Its factors are +1,-1,+2, -2. So we check witha = +1,-1,+2, -2, whether f(a) is zero or not. f(1) = 4 - 12 + 7 + 3 - 2 = 0 < BR> ⇒ x - (1) = (x - 1) is a factor of f(x). Now let us divide f(x) = (4x^{4} - 12x^{3} + 7x^{2} + 3x - 2) by (x - 1) usingSynthetic Division (For detailed explanation of Synthetic Division see Example 1 above.)

Let p(x) = 4x^{3} - 8x^{2} - x + 2This is a third Degree Polynomial, which is to be factorized using Facor Theorem. Here constant term = 2. Its factors are +1,-1,+2, -2. So we check witha = +1,-1,+2, -2, whether f(a) is zero or not. p(1) = 4 - 8 -1 + 2 = -3 ≠ 0 p(-1) = 4(-1)^{3} - 8(-1)^{2} -(-1) + 2 = -4 - 8 + 1 + 2 ≠ 0 p(2) = 4(2)^{3} - 8(2)^{2} -(2) + 2 = 32 - 32 - 2 + 2 = 0. ⇒ x -(2) = (x - 2) is a factor of p(x). Now let us divide p(x) = (4x^{3} - 8x^{2} - x + 2) by (x - 2) usingSynthetic Division (For detailed explanation of Synthetic Division see Example 1 above.)

Are you spending lot of money for math tutors to your child and still not satisfied with his/her grades ?

Do you feel that more time from the tutor and more personalized Math Help to identify and fix the problems faced by your child will help ?

Here is a fool proof solution I strongly recommend and that too With a minuscule fraction of the amount you spent on tutors with unconditional 100% money back Guarantee, if you are not satisfied.

It is like having an unlimited time from an excellent Tutor.

It is an Internet-based math tutoring software program that identifies exactly where your child needs help and then creates a personal instruction plan tailored to your child’s specific needs.

Progressive Learning of Math : Math Factoring

Recently, I have found a series of math curricula (Both Hard Copy and Digital Copy) developed by a Lady Teacher who taught everyone from Pre-K students to doctoral students and who is a Ph.D. in Mathematics Education.

This series is very different and advantageous over many of the traditional books available. These give students tools that other books do not. Other books just give practice. These teach students “tricks” and new ways to think.

These build a student’s new knowledge of concepts from their existing knowledge. These provide many pages of practice that gradually increases in difficulty and provide constant review.

These also provide teachers and parents with lessons on how to work with the child on the concepts.

The series is low to reasonably priced and include
