multiply and simplify

Question

(y^2+10y+25)/(y^2-9)x(y^2+3y)/(y+5)

Answer 1

= (y+5)^2/(y+3)(y-3)) * y(y+3)/(y+5)
= y/(y-3) , y ≠ ±3,-5

Answer 2

Forgot that we had (y+5)^2 upstairs.

y(y+5)/(y+3)

Answer 3

Yup, thanks Steve

Answer 4

(y^2 + 10y + 25)/(y^2 - 9) * (y^2 + 3y)/(y + 5)

(y+5)(y+5)/(y+3)(y-3) * y(y+3)/(y+5)

(y+5)/(y-3) * y/1

y(y+5)/(y-3) or y^2+5y/y-3
