- 0.025 x^{2} - 0.5 x + 60 = 0

x = - 60, x = 40

Solution steps

- 0.025 x^{2} - 0.5 x + 60 = 0

Multiply both sides by

1000

- 25 x^{2} - 500 x + 60000 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 500 ) \pm ( - 500 ) ^{2} - 4 ( - 25 ) \cdot 60000}{2 ( - 25 )}

(- 500)^{2} - 4 (- 25) \cdot 60000 = 2500

x_{1, 2} = \frac{- ( - 500 ) \pm 2500}{2 ( - 25 )}

Separate the solutions

x_{1} = \frac{- ( - 500 ) + 2500}{2 ( - 25 )}, x_{2} = \frac{- ( - 500 ) - 2500}{2 ( - 25 )}

x = \frac{- ( - 500 ) + 2500}{2 ( - 25 )} : - 60

x = \frac{- ( - 500 ) - 2500}{2 ( - 25 )} : 40

The solutions to the quadratic equation are:

x = - 60, x = 40

x (x + 7) = 60

x^{2} + 3 = \frac{7 x}{2}

x^{2} + 14 x + 7 = 0

- a^{2} = - 1

5 = (x - 2) (x - 6)
