Question

X square minus Y square plus 6y Factorise

Answer 1

Answer:

(x^2 - y^2) + 6y

(x+y)(x-y)+6y

i think that the question is incomplete the complete question is

x^2 - y^2 + 6y -9

x^2 - (y^2 - 6y +9)

x^2 - (y^2 - 3y - 3y +9)

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

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

x^2 - (y-3)^2

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

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