x=-5, 1

General Formulas and Concepts:

Order of Operations: BPEMDAS

Standard Form: ax² + bx + c = 0

Quadratic Formula: $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Step-by-step explanation:

Step 1: Define

-h² - 4h + 5 = 0

a = -1

b = -4

c = 5

Step 2: Solve for x

Substitute: $x=\frac{-(-4)\pm\sqrt{(-4)^2-4(-1)(5)} }{2(-1)}$ Simplify: $x=\frac{4\pm\sqrt{(-4)^2-4(-1)(5)} }{2(-1)}$ Exponents: $x=\frac{4\pm\sqrt{16-4(-1)(5)} }{2(-1)}$ Multiply: $x=\frac{4\pm\sqrt{16+20} }{-2}$ Add: $x=\frac{4\pm\sqrt{36} }{-2}$ Evaluate: $x=\frac{4\pm6 }{-2}$ Evaluate: x=-5, 1
