Answer:
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)
