Factoring To Reduc Fractions - 1

Senin, 23 Februari 2026

            Before adding or subtracting fractions factor the denominator. Once the denominator is factored you can determine the LCD.

Examples

From the first fraction we see that the LCD needs x – 4 and x + 1 as factors. From the second fraction we see that the LCD needs x – 1 and x + 1, but x + 1 has been accounted for by the first fraction. The LCD is (x – 4)(x – 1)(x + 1).

Practice

Find the LCD.
