Solving simultaneous equations with one linear and one quadratic Algebraic skills of substitution and factorising are required to solve these equations.

At the beginning of the academic year, students typically learn about constant rates of change; these are linear functions, which appear on graphs as straight lines. Later in the school year, students ...

Google is celebrating the start of the 2025-26 school year with a quadratic equation-themed Doodle. The formula is used in ...

Asymptotic expansions of the distributions of the linear and the quadratic discriminant functions are derived. The expected misclassification probabilities of these two functions are compared when the ...

Quadratic equations are polynomials, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have ...

Unlike a linear, graph, a quadratic graph has an equation which includes an x squared term.

Many former algebra students have painful memories of struggling to memorize the quadratic formula. A new way to derive it, overlooked for 4,000 years, is so simple it eliminates the need.
