We will learn how to solve these types of equations as we continue in our study of algebra. In fact, many polynomial equations that do not factor do have real solutions. This does not imply that equations involving these unfactorable polynomials do not have real solutions. We have seen that many polynomials do not factor. In general, for any polynomial equation with one variable of degree \(n\), the fundamental theorem of algebra guarantees \(n\) real solutions or fewer. Notice that the degree of the polynomial is \(3\) and we obtained three solutions. Determine the discriminant by evaluating the expression b 2 - 4ac where a is the coefficient of x 2, b the coefficient of x, and c the constant term in a quadratic equation.Ĭan you tell if the roots of a quadratic equation are equal or unequal without solving it?

Solve Quadratic Equations by Completing the SquareĬomplete the square of the given quadratic equation and solve for the roots. If you need help factoring, make sure to check out the lesson on factoring quadratics. We need two numbers that multiply to -14 and the middle terms need to add up to -5x. Now that its set equal to 0, we need to factor it. Isolate the x 2 term on one side of the equation and the constant term on the other side, and solve for x by taking square roots. We can do this by subtracting 14 from both sides. This worksheet provides practice in solving quadratic equations by factoring, with four sections of different types of quadratic equations.
