Quadratic Equations and Coefficients Quiz

The coefficients a, b, and c in a quadratic equation represent known numbers, where a ≠ 0. They are respectively called the quadratic coefficient, the linear coefficient, and the constant coefficient or free term.

The values of x that satisfy the equation are called solutions of the equation, and roots or zeros of the expression on its left-hand side.

A quadratic equation has at most two solutions. If there is only one solution, one says that it is a double root.

<p>If all the coefficients are real numbers, there are either two real solutions, or a single real double root, or two complex solutions that are complex conjugates of each other.</p> Signup and view all the answers
