General Formulas and Concepts:

Algebra I

  • Expanding by FOIL-ing (First Outside Inside Last)
  • Combining Like Terms

Step-by-step explanation:

Step 1: Define expression

(p² - 4)(9 - q²) + 24pq

Step 2: Simplify

  1. Expand by FOIL-ing:                    9p² - p²q² - 36 + 4q² + 24pq
  2. Combine like terms:                    -p²q² + 9p² + 4q² + 24pq - 36

Answer:

9p^2-p^2q^2-36+4q^2=24pq

Step-by-step explanation:

multiply the parentheses

multiply the term in the first (   ) by each term in the second (   )   (FOIL)

9p^2-p^2q^2-4x9-4x(-q^2)=24pq

Multiply the numbers (multiplying two negatives = a positive )

9p^2-p^2q^2-36=4q^2+24pq

Hope that helps
