Step-by-step explanation:

The first step is to rearrange the given quadratic equation so that it will take the form of the standard quadratic equation which is expressed as

ax² + bx + c = 0

The given quadratic equation is expressed as

2 = - x + x² - 4

Rearranging it, we would subtract 2 from the left hand side and the right hand side of the equation. It becomes

2 - 2 = - x + x² - 4 - 2

- x + x² - 6 = 0

x² - x - 6

a = 1

b = - 1

c = - 6

Substituting into the quadratic formula, it becomes

x = [- (- 1) ± √(- 1)² - 4(1)(- 6)] /2(1)
