Solution
Let's break down and analyze the mathematical work in the image.
Part 1 (Multiplication of Rational Expressions):
The first part involves simplifying the expression:
Step-by-Step Process:
-
Factor the terms:
- The first fraction:
- The second fraction:
-
Simplify the product: Combine the two fractions:
-
Cancel common terms:
- appears in both the numerator and the denominator, so it cancels out.
- also cancels out.
- This leaves:
Thus, the simplified expression is:
Part 2 (Simplification of Rational Expression):
The second part asks you to simplify:
Step-by-Step Process:
-
Factor the quadratic in the denominator of the first term: Now the expression becomes:
-
Find a common denominator: The common denominator between the two fractions is , so rewrite the second fraction with this denominator:
-
Combine the fractions:
-
Simplify the numerator: Expand the terms in the numerator: So the expression becomes:
-
Cancel common terms: The terms cancel out, leaving:
Thus, the simplified expression is:
