Question

Factor'se the following Polynominal
4x² - 121y²​

Answer 1

Answer:

(2x+11y)(2x-11y) is the correct answer

Step-by-step explanation:

4x² - 121y² = (2x)² - (11y)²

using identity : a²-b² = (a+b)+a-b)

4x² - 121y² = (2x+11y)(2x-11y)

Answer 2

Answer:

( 2x + 11y ) ( 2x - 11y )

Step-by-step explanation:

4x² - 121y²

= ( 2x )² - ( 11y )²

a² - b² = ( a + b ) ( a - b ) { Identity / formula }

Here,

a = 2x

b = 11y

( 2x )² - ( 11y )² = ( 2x + 11y ) ( 2x - 11y )
