Question

4x2-9y2-6x-9y factories it , I will mark as brainleist.​

Answer 1

Anr:

Step-by-step explanation:

4x2-6x-9y2-9y=0

4x2-9y2-6x-9y=0

(2x+3y) (2x-3y) -3(2x+3y) =0

(2x+3y) [(2x+3y) -3]=0

(2x+3y) (2x+3y-3) =0

Answer 2

Concept-

Use the identity, a² - b² = ( a + b ) ( a - b ) to factorize the given equation.

Given-

Equation is given as 4x²-9y²-6x-9y.

Find-

Factorize the above given equation.

Solution-

4x²-9y²-6x-9y

Put this equation equal to 0-

4x²-9y²-6x-9y=0

(2x)² - (3y)² - 3 ( 2x + 3y) = 0

Use the identity, a² - b² = ( a + b ) ( a - b )

( 2x + 3y ) (2x + 3y ) - 3 ( 2x + 3y )=0

Taking 2x + 3y as common,

( 2x + 3y ) ( 2x - 3y - 3 )

Therefore , factorization of 4x²-9y²-6x-9y is ( 2x + 3y ) ( 2x - 3y - 3 ).
