Roots of Quadratic Equations and the Quadratic Formula Roots are also called x-intercepts or zeros. A quadratic function is graphically represented by a parabola with vertex located at the origin, below the x-axis, or above the x-axis. Therefore, a quadratic function may have one, two, or zero roots.

Now we can solve a Quadratic Equation in 5 steps: Step 1 Divide all terms by a (the coefficient of x2). Step 2 Move the number term (c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

To check your answers, you can substitute both values directly into the original equation and see if you get a true sentence for each. Both solutions check. You can use the Principle of Zero Products to solve quadratic equations in the form ax2 + bx + c = 0. First factor the expression, and set each factor equal to 0.

Step 1: To use the quadratic formula, the equation must be equal to zero, so move the –5 back to the left hand side. Step 2: Identify a, b, and c and plug them into the quadratic formula. In this case a = –3, b = 6, and c = 5. Step 3: Use the order of operations to simplify the quadratic formula.

A quadratic equation is an equation of the form ax^2 + bx +c = 0 where x is an unknown, a, b and c are constants with a not equal to 0. ... A quadratic function is a function of a single variable x, with a value y determined by a formula of the form: y = ax^2 + bx + c, where a, b and c are constants.
