Re: solve by factoring
Or use solution to quadratic equation:
\(\displaystyle A\cdot x^2 \, + \, B\cdot x \, + \, C \, = \, A\cdot (x \, - \, x_1)\cdot(x \, - \, x_2)\)
where
\(\displaystyle x_{1,2} \, = \, \frac{-B \pm \sqrt{B^2 \, - \, 4AC}}{2A}\)

WHY do you need help with that? Factoring not taught by teacher?jmarino5892 said:can you help with this
