Question

1.
Factorise:
(a) 4x² - y²
2.
36 25
Factorise:​

Answer 1

Explanation:

The answer is :

(2x)²-(y)²

Therefore now we have it as

a²-b² format which=(a+b)(a-b)

Therefore,

on factorizing....

(2x-y)(2x+y)

Hope it helps you

Pls mark it Brainliest...(pls)

Answer 2

Answer:-

4x^2 - y^2

(2x)^2 - (y)^2. [ a^2 - b^2 = (a+b)(a-b) ]

(2x+y)(2x-y)

Therefore on factorising :-

(2x+y)(2x-y)

Hope it helps you!!

I am not forcing you to mark me as brainliest

But the answer which help you the most mark that as brainliest
