Solve for what?

2. anonymous

its a quadratic equation so :/

3. anonymous

y = x^2 + 3x + 2 Factor the equation. y = (x+2)(x+1) Set the equation equal to zero. y = (x+2)(x+1) = 0 x+2 = 0 x = -2 x+1 = 0 x = -1 Therefore, x = -1 and x = -2.

thanks

Oh, you mean solve for y = 0. You should be more specific. You could just as easily solve for y = $$\pi$$ or x = 15, or anything really.
