quadratic formula b0. Write the solution in inequality notation or interval notation. Quadratics are polynomials whose highest power term has a degree of 2.
Ax 2 bx c 0. X b b 2 4 a c 2 a. X a x b 0 when a b then a x or x b.
Where x is an unknown a is referred to as the quadratic coefficient b the linear coefficient and c the constant.
Substitute 1 for a 2x for b and xax a for c in the quadratic formula 2ab b24ac. Is used to solve quadratic equations where a 0 polynomials with an order of 2 a x 2 b x c 0. The standard form of a quadratic equation is ax 2 bx c 0 when a 0 and a b and c are real numbers. All quadratic equations can be put in standard form and any equation that can be put in standard form is a quadratic equation.
