Exercises Polynomials and factoring

Example 8.2 from Elementary Algebra, 8.1 Simplify Rational Expressions

Simplify Rational Expressions: example 8.2

Evaluate $\frac{2 x + 3}{3 x - 5}$ for each value:

ⓐ $x = 0$ ⓑ $x = 2$ ⓒ $x = −3$

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
ⓐ

Simplify.

ⓑ

Simplify.

ⓒ

Simplify.

Your turn

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

Evaluate $\frac{y + 1}{2 y - 3}$ for each value:

ⓐ $y = 1$ ⓑ $y = −3$ ⓒ $y = 0$

How did it go?
