Here x is the variable and a b and c are constants where a 0. What does it look like. Quadratic equations are equations whose highest power in the variables is 2.
This is generally true when the roots or answers are not rational numbers.
The standard form is ax² bx c 0 with a b and c being constants or numerical coefficients and x is an unknown variable. In this case the equation does not have real roots. Here are a few quadratic functions. This lesson will cover the definition and the solution of a quadratic equation.
