Solve by the quadratic formula and simplify
WebThis formula is called the quadratic formula: The quadratic formula is composed of a solution (x) and coefficients. The coefficients are the values of a, b, and c. Below is a variation of the quadratic formula: If you take a good look at both formulas, you will notice that the quadratic formula and its variation both contain b 2-4ac. WebNov 5, 2024 · The Quadratic Formula - One x-intercept. An x-intercept is the point where a parabola crosses the x -axis. This point is also known as a zero , root, or solution. Some quadratic functions cross the x -axis twice. Some quadratic functions never cross the x -axis. There are four different methods for finding the x -intercept of a Quadratic Function:
