Question

How to factorize 49$x^{2}$ - 16$y^{2}$].​

Pls help

Answer 1

Answer:

Rewrite 49x2 49 x 2 as (7x)2 ( 7 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=7x a = 7 x and b

Answer 2

Step-by-step explanation:

Multiply the number

49 . 2 - 16y 2

98 -16y 2

Rearrange the terms

98 -16y ^2

-16y^2 + 98

Common factor

Factor by grouping

49 . 2 -16^2

-2 (8y^2 - 49)
