General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
5x(3 - 12x) - 3(4 - 20x²)
<u>Step 2: Simplify</u>
- Distribute: 15x - 60x² - 12 + 60x²
- Combine like terms: 15x - 12
Use copy dot flip to solve.
= 3 5/7 / 2/1
= 26/7 * 1/2 (Turned into improper fraction)
= 26/14 (Improper Fraction Answer)
= 1 12/14 (Mixed Number Answer Simplified)
= 1 6/7 (Final Answer Simplified)
Hope This Helped! Good Luck!
