Question

If (x2 – 4) ÷ (x + 2) = x – 2, which polynomial should fill in the blank below?

Answer 1

Answer:

Step-by-step explanation:

Alright, lets get started.

Given that:

$\frac{(x^2-4)}{(x+2)}=(x-2)$

(x-2) could be written as $\frac{x-2}{1}$

$\frac{(x^2-4)}{(x+2)}=\frac{(x-2)}{1}$

Doing cross multiply

$(x+2)(x-2)=(x^2-4)*1$

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

It means the blank part is (x-2)   :    Answer

Hope it will help :)

Answer 2

(x + 2) (x - 2) = x^2 – 4

answer
B.x – 2
