Question

factorise 75x^2-3(x-y)^2​

Answer 1

Answer:

72x²+6xy-3y²

Step-by-step explanation:

75x²- 3(x-y)² = 75x² - 3 (x²-2xy + y²) = 75x²-3x²+6xy-3y²

                                                          = 72x²+6xy-3y²

Answer 2

Answer:

75x^2-3(x-y)^2= 75x^2 - 3x^2-3y^2

                       = 3(25x^2-x^2-y^2)

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

                       = 3(6x-y)(4x+y)
