Question

facctorise the following 144x^2-25y^2 step by step

Answer 1

Answer:

144x^2 -25y^2

(12x)^2 -(5y)^2. using identity (a2 -b2 = a+b)(a-b)

we get

(12x+5y)(12x-5y)

Answer 2

Answer:

step1:we have to convert 144x^2-25y^2 into (12x)^2- (5y)^2

step2: apply difference of two squares formula :x^2- y^2=(x+y) (x-y)

step3:(12x)^2 ( 5y)^2)=(12x-5y)^2

step4:(12x+5y) (12x-5y)
