Remainder And Factor Theorems
Bayani Gaba-gaba
Dividing one polynomial by another can be slow. The remainder and factor theorems give you a shortcut so powerful it feels like cheating: you can find the remainder of a division, or test whether something is a factor, just by substituting a single number. No long division required.
In this lesson you will meet the remainder theorem, which says the remainder when a polynomial is divided by \((x-a)\) is simply \(f(a)\), and the factor theorem, its special case when that remainder is zero. Together they are the key to factorising and solving cubic equations, a staple of the higher-level syllabus.
