Solving a quadratic function
WebThe solutions to quadratic equations are called roots. Roots are the x -intercepts ( zeros ) of a quadratic function. For every quadratic equation, there is a related quadratic function. For example, if you are given the quadratic equation. x 2 + 5 x + 4 = 0, the related quadratic function is. f ( x) = x 2 + 5 x + 4. WebFeb 14, 2024 · Step 5: Solve the equation. Substitute in the values. Distribute. This is a quadratic equation; rewrite it in standard form. Solve the equation using the Quadratic Formula. Identify the \(a,b,c\) values. Write the Quadratic Formula. Then substitute in the values of \(a,b,c\). Simplify. Figure 9.5.13: Rewrite to show two solutions.
