Question

Factorize 2x2 – 18y?​

Answer 1

Answer:

Rewrite 9y2 9 y 2 as (3y)2 ( 3 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=x and b=3y b = 3 y . Factor. Multiply 3 3 by −1 - 1 .

Answer 2

Answer:

4-18y=0

-18y=-4

y=2/9

hope it help you.
