Question: how to find the roots of a quadratic equation by factoring?
Answer: Since the roots of a function are the points at which y = 0, we can find the roots of y = ax2 + bx + c = 0 by factoring ax2 + bx + c = 0 and solving for x. We can also find the roots of y = ax2 + bx + c = 0 using the quadratic formula, and we can find the number of roots using the discriminant.
