Question

factorize 25x^2 - 36y^2​

Answer 1

Answer:

Rewrite 25x2 25 x 2 as (5x)2 ( 5 x ) 2 . Rewrite 36y2 36 y 2 as (6y)2 ( 6 y ) 2 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 - b 2 = ( a + b ) ( a - b ) where a=5x a = 5 x and b=6y b = 6 y .
