Take this formula and do it by your own
Complete the square of ax2 + bx + c = 0 to arrive at the Quadratic Formula. Divide both sides of the equation by a, so that the coefficient of x2 is 1. Rewrite so the left side is in form x2 + bx (although in this case bx is actually ). Since the coefficient on x is , the value to add to both sides is .
