There are many ways to solve quadratics. Below is a picture representing the graph of y x² 2x 1 and its solution. Compute the discriminant and state the number and type of solutions.
Press to solve the equation.
Ax 2 bx c 0 where x is an unknown a is referred to as the quadratic coefficient b the linear coefficient and c the constant. The Quadratic Formula uses the a b and c from ax 2 bx c where a b and c are just numbers. When b 2 4 a c 0 there are two real roots. Press to solve the equation.
