[PDF] 32 The Factor Theorem and The Remainder Theorem

In this case, The Remainder Theorem tells us the remainder when p(x) is divided by (x - c), namely p(c), is 0, which means (x - c) is a factor of p What we

[PDF] Remainder Theorem and Factor Theorem 101360_6remainder_theorem_and_factor_theorem.pdf There are two important theorems to be applied when factoring polynomials:

Remainder Theorem:When a polynomial, f(x), is divided by x-a, the remainder is equal to f(a). If the

remainder is zero, then x-ais a factor of the polynomial. Factor Theorem:x-ais a factor of f(x) if and only if f(a) = 0 Ex: What is the remainder when 8x4-3x2+ 5x-9 is divided by x+ 1? Ex. Determine the remainder when 2x2+ 5x-4 is divided by 2x1, without dividing. Ex. If (x2) is a factor of f(x)= x3-7x + k, determine the value of k. Ex: When 2x4+ ax3-5x2+ bx-11 is divided by x-1 the remainder is -13. When it is divided by x+ 2 the remainder is -7. Find aand b.

Remainder Theorem and Factor Theorem

If none of the factors of the constant term give a remainder of 0, then the factor must be of the form

(ax b). Substitute values of the form b/awhere bare factors of the constant term and aare factors of

the leading coefficient. Ex. Determine a factor of P(x) = 30x3+ 17x2-3x-2.

Start by trying factors of the constant term:ƒ

P(1) = 42

P(-1) = -12

P(2) = 300

P(-2) = -168

Try factors of 2 over factors of 30:ƒ

Therefore there is a root at x= -1/2 and the factor is (2x+ 1). Be sure to always write factors in the form (ax + b) NOT .
