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

Step-by-step explanation:

Step 1: Define

Identify variables

x² - 7x - 8

↓

a = 1, b = -7, c = -8

Step 2: Solve for x

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