Quadratic Equation

A quadratic equation has the general form $ax^{2}+bx+c=0$ with $a\neq 0$. Its highest power is two, so it can have up to two roots.

We solve it by factorising, completing the square, or using the formula $x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}$.

You meet Quadratic Equation in the Quadratic Functions chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.

Our teachers make sure a student can not only recite what Quadratic Equation means but use it fluently in a full solution.

Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Quadratic Equation (EN) · Persamaan Kuadratik (BM) · 二次方程 (中文)
