Rational Expressions & Functions

A2.E.1Simplify01/04

Simplify rational expressions.

Step01of 04

A rational expression is a fraction of polynomials. To simplify: factor numerator and denominator, then cancel common factors.

Always factor first, never cancel terms. $\frac{x + 3}{x}$ does NOT simplify to $3$ — the $x$ in the numerator isn't a factor.
