An algebraic expression where both the numerator and the denominator are polynomials e.g. The expression above has an excluded value of zero. ... To simplify a rational expression you have to eliminate all factors that are common of the numerator and the denominator.
How do you simplify rational expressions step by step?
- Step 1: Factor the numerator and the denominator.
- Step 2: List restricted values.
- Step 3: Cancel common factors.
- Step 4: Reduce to lowest terms and note any restricted values not implied by the expression.
