The standard form of a quadratic equation is y = ax^2 + bx + c, so you may need to move terms around to make the equation take this form. A quadratic equation might be written in the vertex form, which is y = a(x - h)^2)... More »

Solve quadratic equations by graphing, using square roots, factoring, completing the square or using the quadratic formula. Determine the most appropriate method by considering the particular situation. More »

To find the equation of a parabola, substitute the vertex coordinates for h and k, substitute the coordinates of another point on the parabola for x and y and then solve for a. The equations will differ depending on whet... More »

To solve two-step equations, simplify both sides of the equation by removing extra terms, then remove coefficients. It's also possible that a variable will exist on both sides of the equation. In this case, you need to i... More »

Solving trinomial equations is a matter of determining the degree of the trinomial factoring according to the degree and the terms themselves and by then verifying that the factors found are the actual roots of the equat... More »

The quadratic function "f(x) = ax2 + bx + c" is the standard form for quadratic equations. F(x) is representative of the output, and x is the variable, also called the unknown. A, b and c in the equation are known values... More »

A linear equation solver takes a specified number of linear equations and solves them using established methods. Make sure to review what each program/website is capable of solving because each is slightly different. More »
