General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right<u> </u>

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x(x² + 4x - 5)

f(-2) is x = -2

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x  </em>[Function]:                                                                             f(-2) = 3(-2)[(-2)² + 4(-2) - 5]
  2. [Brackets] Evaluate exponents:                                                                     f(-2) = 3(-2)[4 + 4(-2) - 5]
  3. [Brackets] Multiply:                                                                                         f(-2) = 3(-2)[4 - 8 - 5]
  4. [Brackets] Subtract:                                                                                        f(-2) = 3(-2)[-4 - 5]
  5. [Brackets] Subtract:                                                                                        f(-2) = 3(-2)(-9)
  6. Multiply:                                                                                                           f(-2) = -6(-9)
  7. Multiply:                                                                                                           f(-2) = 54
