quadratics
Algebra with squares
Quadratics is the branch of algebra dealing with quadratic equations—those where the highest power of the unknown is two.
A quadratic equation takes the form ax² + bx + c = 0, solved by factoring, completing the square, or applying the quadratic formula.
She struggled with quadratics until the formula clicked.
The term also refers collectively to such equations: We're covering quadratics this semester.
