Question

factorise:(x-2y)^2+7(x-2y)+12

Answer 1

${(x - 2y)}^{2} + 7(x - 2y) + 12 \\ {(x - 2y)}^{2} + 4(x - 2y) + 3(x - 2y) + 12 \\(x - 2y)(x - 2y + 4) + 3(x - 2y + 4) \\ (x - 2y + 4)(x - 2y + 3)$
please follow me

Answer 2

Answer:

=> (x-2y)^2+7(x-2y)+12

=> (x-2y)^2+4(x_2y)+3(x-2y)+12

=> (x-2y)(x-2y+4)+3(x-2y+4)

=> (x-2y+4)(x-2y+3)
