Factor, cancel, multiply, simplify, and preserve excluded values in rational expressions.
20 rational-expression products with restrictions, worked simplification, and error analysis.
This practice set focuses on multiplying algebraic fractions efficiently and correctly. Most problems require factoring first so that complete common factors can be canceled before numerators and denominators are multiplied.
The test also emphasizes excluded values from the original denominators. A canceled factor still creates a restriction because the original expression was undefined at that value.
Factoring differences of squares and trinomials, canceling common factors, reducing numerical coefficients, applying exponent rules, tracking restrictions, recognizing reciprocals, and simplifying application models.
Do not cancel x across x + 3, discard excluded values after cancellation, confuse 4 − x with x − 4, or cancel more copies of a repeated factor than actually appear.
Immediate explanations show the factorization, cancellation, final restrictions, and the specific error behind each distractor.
