How to solve quadratic applications
WebIf you have a general quadratic equation like this: ax^2+bx+c=0 ax2 + bx + c = 0 Then the formula will help you find the roots of a quadratic equation, i.e. the values of x x where this equation is solved. The quadratic formula x=\dfrac {-b\pm\sqrt {b^2-4ac}} {2a} x = 2a−b ± b2 − 4ac It may look a little scary, but you’ll get used to it quickly! WebQuadratic Equation Solver We can help you solve an equation of the form "ax2 + bx + c = 0" Just enter the values of a, b and c below: Is it Quadratic? Only if it can be put in the form ax2 + bx + c = 0, and a is not zero. The name comes from "quad" meaning square, as the variable is squared (in other words x2 ).
