Find the exact solution of - x2 + 7x + 5 = 0 by using the Quadratic Formula.

The answer to your question is:

x 1 = - 0.65

x2 = 7.65

Step-by-step explanation:

Equation - x² + 7x + 5 = 0

a = - 1

b = 7

c = 5

Quadratic formula x = - b ±√ (b² - 4ac) / 2a

x = - 7 ± √ (7² - 4 (-1) (5) / 2 (-1)

x = - 7 ± √ (49 + 20) / - 2

x = - 7 ± √69 / - 2

x = - 7 ± 8.3 / - 2

x1 = - 7 + 8.3 / - 2 x2 = - 7 - 8.3 / - 2

x 1 = - 0.65 x2 = 7.65
