Question

(a square-4)÷(a-2) please do step by step​

Answer 1

(a + 2)

Explanation:

`(a^(2) - 4)/(2 - 2)`

Now first work for the numerator.

=
`(a^(2) - 2^(2) )/(a - 2)`

numerator is in the form of a^2 - b^2 formula , SO,

=(a - 2)(a + 2)/a-2

(a-2) of both numerator and denominator gets cancel.

=(a + 2)
