Please help! -3n+147=0

Mathematics
1 answer:
horrorfan [7]3 years ago
6 0

Answer:

n = ±7

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving quadratics

Step-by-step explanation:

<u>Step 1: Define equation</u>

-3n² + 147 = 0

<u>Step 2: Solve for </u><em><u>n</u></em>

  1. Subtract 147 on both sides:                    -3n² = -147
  2. Divide -3 on both sides:                          n² = 49
  3. Square root both sides:                           n = ±7
