If x+y = -1, and xy= -12, what is the value of (x+3) (y+3) ?

Here are my hints. You can solve it yourself

1/ xy = -12      -->      x = -12/y

2/ (-12/y) + y = -1      -->     -(12/y) + (y²/y) = -1    -->    -12 + y² = -y   -->    y²+y-12=0

3/ From y²+y-12=0 we can find y then use y to find x and then do your

(x+3) * (y+3)
