Question

(x²-4) / (x+2) please solve it

Answer 1

(x²-4)/(x+2)

=(x+2)(x-2)/(x+2) [a²-b²=(a+b)(a-b)]

Cancelling (x+2) in numerator and denominator,

Ans is (x-2)

Answer 2

Answer:

$x-2$

Step-by-step explanation:

It is a very easy question to solve.

In the question actually we are given a equation we need to minimize the equation. To solve the question we need to know a basic formulla , which is  $(a-b)^{2}$. We all know this formulla ...

$(a-b)^{2}\\=(a+b)(a-b)$

Here we are given  $\frac{x^{2}-4 }{x+2}$. So according to the discussion if we start to solve the question then the following steps are...

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