Simplifying
Rationalize the denominator of , where the denominator contains an integer coefficient multiplied by a square root.
Step 1 — Multiply both the numerator and the denominator by . Only the radical portion of the denominator needs to be used as the multiplying factor:
Step 2 — Simplify. In the denominator, , so . In the numerator, :
Step 3 — Remove common factors. The numerator coefficient and the denominator share a common factor of . Factor and cancel: .
The simplified result is . When the denominator has a coefficient in front of the radical, multiply only by the square root — the coefficient stays and becomes part of the product in the denominator. After rationalizing, always check whether the resulting fraction can be reduced further by canceling common numerical factors between the numerator and denominator.
