Example 8.45 from Elementary Algebra, 8.4 Add and Subtract Rational Expressions with Unlike Denominators

Add and Subtract Rational Expressions with Unlike Denominators: example 8.45

Subtract: $\frac{x}{x - 3} - \frac{x - 2}{x + 3} .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Subtract: $\frac{y}{y + 4} - \frac{y - 2}{y - 5} .$
