Question

The roots of the quadratic equation x2 + bx + c = 0 are

​

Answer 1

The Quadratic Formula 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 .

Answer 2

The roots are x=b+c is our correct answer
