Question

The factors of 25xsq-16ysq

Answer 1

Step-by-step explanation:

Rewrite 25x2 25 x 2 as (5x)2 ( 5 x ) 2 . Rewrite 16y2 16 y 2 as (4y)2 ( 4 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=4y b = 4 y .
