Question

divide:
4. (x²-4) by (x+2)
Step by Step explanation in copy.​

Answer 1

Answer:

(x-2)

Step-by-step explanation:

(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:

$\frac{(x²-4)}{x + 2}$

By using identity (a²-b²) = (a+b)(a-b)

$\frac{(x+2)(x-2)}{x + 2}$

x+2 and x+2 will be canceled so

result obtained will be

$x + 2$
