x-8 is not a factor of p(x) = x^3-9x^2+12x-17

Step-by-step explanation:

In order to check whether a term is factor of given expression or not we put the value in the expression. If the expression is zero, then the value is a factor otherwise not.

Given polynomial is:

p(x) = x^3-9x^2+12x-17

We have to check if x-8 is factor of given polynomial or not. for that purpose we have to put

x-8 = 0\\x = 8

Putting in the polynomial

p(x) = (8)^3 - 9(8)^2+12(8)-17\\= 512 - 8(64) + 96 - 17\\= 512-512+96-17\\=79

Hence,

x-8 is not a factor of p(x) = x^3-9x^2+12x-17

Roman55 [17]

Answer:

(8x-7)(8x+7)

Step-by-step explanation:

This is a difference of squares polynomial of the form a^2-b^2=(a+b)(a-b). Since 64 and 9 are both perfect squares then take the square root of each so a=8 and b=7.

Factors:(8x-7)(8x+7)
