Write the quadratic equation in factored form. Be sure to write the entire equation. x 2 + x - 12 = 0

We want -12 in the end, so pick two numbers that multiplied together yield -12: (x-3)(x+4) = 0

OpenStudy (anonymous):

^ multiplied to give you -12, and add to give you 1 (because the coefficient of the x term is 1).
