The most popular method to solve a quadratic equation is to use a quadratic formula that says x -b ± (b2 - 4ac)/2a. Furthermore, this also doesn't require you to remember the quadratic formula, for exams where you are not provided with the formula, although it's probably worth remembering the quadratic formula anyway.įor example, I will solve the following equation for x. A quadratic equation is of the form ax2 + bx + c 0, where a, b, and c are real numbers. The quadratic formula gives solutions to the quadratic equation ax2+bx+c0 and is written in the form of x (-b (b2 - 4ac)) / (2a) Does any quadratic equation have two solutions There can be 0, 1 or 2 solutions to a quadratic equation. This method of solving equations is much faster than typing in the quadratic formula and doesn't require you to manually flip the + and − signs in the quadratic formula as ± can't be entered directly into the calculator. The quadratic solver calculator can solve all quadratic equations, regardless of the nature of the solution (real or complex). It shows you the steps and explanations for each problem, so you can learn as you go. This also works with quadratic equations which have no real roots: the roots can be provided as complex numbers. Symbolab is the best step by step calculator for a wide range of physics problems, including mechanics, electricity and magnetism, and thermodynamics. Instead of needing to enter the quadratic formula with a, b and c substituted, you can simply insert a, b and c into the quadratic equation solver and the calculator will calculate the roots for you and display them onscreen as x 1 and x 2.
Quadratic equations can be solved using the quadratic formula which is stored on the calculator and can be used from the equation mode.
