Answer:
y² + bs²y - 6b²s⁴
General Formulas and Concepts:
- Expand by FOIL (First Outside Inside Last)
- Exponent Power Rule:
Step-by-step explanation:
<u>Step 1: Define expression</u>
(y - 2bs²)(y + 3bs²)
<u>Step 2: FOIL</u>
- First: y · y = y²
- Outside: y · 3bs² = 3bs²y
- Inside: -2bs² · y = -2bs²y
- Last: -2bs² · 3bs² = -6b²s⁴
<u>Step 3: Simplify</u>
- Combine: y² + 3bs²y - 2bs²y - 6b²s⁴
- Combine like terms: y² + bs²y - 6b²s⁴
