Question

Factorise 4x square-ysquare/25​

Answer 1

Step-by-step explanation:

4x^2=(2x)^2

y^2/25=(y/5)^2

(2x)^2-(y/5)^2

(a+b)(a-b)=a^2-b^2

so same here

we get

after factorisation

(2x-y/5)(2x+y/5)

expression gets factorized

Answer 2

Step-by-step explanation:

4x square=(2x) square

y square/25=(y/5)square

(2x) square-(y/5)square

(a+b)(a-b) =a square -b square

(2x+y/5)(2x-y/5)
