Question

4x2-9(X+y)²

factorise​

Answer 1

Answer:  ( 5x+ 3y)(-x -3y)

Step-by-step explanation:

4x²- 9(X+y)²=  (2x)² - (3{X+y})²  

                      =( 2x + 3{X+y}) (2x- 3{X+y})               a² - b² = (a+b)(a-b)      

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

                     = ( 5x+ 3y)(-x -3y)
