Question

y=ײ(×+2)³

Answer 1

I don't mind helping to find answers, but I resent having to provide the questions as well.

and your keyboard has a perfect;y good x key -- why not use it?

Answer 2

y=x^2(x+2)^3
(x+2)^3= (x+2)(x+2)(x+2)
=(x^2+4x+4)(x+2)
=x^3+2x^2+4x^2+8x+4x+8
=x^3+6x^2+12x+8
=x^2(x^3+6x^2+12x+8)
=x^5+6x^4+12x^3+8x^2
