Question

factorise 25 x square - 10 X + 1 - 36 x y square​

Answer 1

Explanation:

I think so question is. 25x^2-10x+1-36y^2

25x^2-10x+1=36y^2=(5x)^2-2( 5x+1)^2-(6y)^2

We know that by formula,

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

(5x)^2-2(5x)+1^2 can written as (5x-1)^2

25x^2-10x+1-36y^2=((5x-1)+6y)(5x-1)-6y)

OR

25x^2-10x+1-36y^2

(5x)^2-2(5)(1)+1^2-(6y)^2

(5x-1+6y)(5x-1+6y)

Answer is (5x-1+6y)(5x-1+6y)
