Question

using identities and factorisation , divide the following : (x-2)²+9(x-2) by (x+7)​

Answer 1

Answer:

x-2

Step-by-step explanation:

(x-2)^2=x^2+4-2x

=x^2 +4-4x+9x-18=x^2+5x-14=(x-2)(x+7)

dividing=(x-2)(x+7)/(x+7)=x-2

Answer 2

Step-by-step explanation:

2x - 4 + 9x - 18 × x + 7

2x + 9x -18x + 7

11x - 18x + 7

7x + 7

x = 0
