Order of Operations: BPEMDAS

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

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Factoring
  • Quadratic Formula: \displaystyle x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}

<u>Algebra II</u>

  • Imaginary Numbers: √-1 = i

Step-by-step explanation:

<u>Step 1: Define</u>

x² + 2x = -2

<u>Step 2: Identify Variables</u>

  1. Rewrite Quadratic in Standard Form [Addition Property of Equality]:        x² + 2x + 2 = 0
  2. Break up Quadratic:                                                                                        a = 1, b = 2, c = 2

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [Quadratic Formula]:                                                \displaystyle x=\frac{-2 \pm \sqrt{2^2-4(1)(2)}}{2(1)}
  2. [√Radical] Evaluate exponents:                                                                     \displaystyle x=\frac{-2 \pm \sqrt{4-4(1)(2)}}{2(1)}
  3. Multiply:                                                                                                           \displaystyle x=\frac{-2 \pm \sqrt{4-8}}{2}
  4. [√Radical] Subtract:                                                                                        \displaystyle x=\frac{-2 \pm \sqrt{-4}}{2}
  5. [√Radical] Factor:                                                                                        \displaystyle x=\frac{-2 \pm \sqrt{-1}\sqrt{4}}{2}
  6. [√Radicals] Simplify:                                                                                       \displaystyle x=\frac{-2 \pm 2i}{2}
  7. Factor:                                                                                                             \displaystyle x=\frac{2(-1 \pm i)}{2}
  8. Divide:                                                                                                             \displaystyle x = -1 \pm i
