Question

solve the equations, y(y+2) = 3

Answer 1

distribute the y first: y^2+2y = 3
this is equivalent to y^2+2y-3 = 0
when you factor, you get (y-1)(y+3) = 0
y = 1 and y = -3

Answer 2

wait, I dont get it yet. how did you get (y-1)(y+3) ?

Answer 3

when you factor. do you know how to factor?
