<u>Algebra I</u>

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

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

x² - 7x - 8

↓

<em>a</em> = 1, <em>b </em>= -7, <em>c</em> = -8

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

  1. Substitute in variables [Quadratic Formula]:                                                  \displaystyle x=\frac{7 \pm \sqrt{(-7)^2-4(1)(-8)}}{2(1)}
  2. [√Radical] Evaluate exponents:                                                                       \displaystyle x=\frac{7 \pm \sqrt{49-4(1)(-8)}}{2(1)}
  3. [√Radical] Multiply:                                                                                           \displaystyle x=\frac{7 \pm \sqrt{49 + 32}}{2(1)}
  4. [√Radical] Add:                                                                                                 \displaystyle x=\frac{7 \pm \sqrt{81}}{2(1)}
  5. [√Radical] Evaluate:                                                                                         \displaystyle x=\frac{7 \pm 9}{2(1)}
  6. Multiply:                                                                                                             \displaystyle x=\frac{7 \pm 9}{2}
  7. Add/Subtract:                                                                                                    \displaystyle x=\frac{-2}{2}, \ \frac{16}{2}
  8. Divide:                                                                                                               \displaystyle x=-1, \ 8
