In this video the tutor shows how to simplify a quadratic formula result. You can solve a quadratic equation using the quadratic formula. The first thing you have to do when given the quadratic equation is bring all the terms to one side so that you have a zero on the other side of the equals to sign. Now the formula to calculate the roots of the quadratic equation ax*x + bx + c = 0 is x = (-b + root of(b*b - 4*a*c) ) / 2 * a. The other root can be obtained by using the minus sign before the square root in the previous formula. Now to compute the roots just extract the values of a, b, c from any quadratic equation and substitute them in the formula. You should also simplify the value of the square root to obtain the roots in the simplest form. This video shows how to calculate the roots of an equation using the quadratic roots formula.
