- 0.5 x^{2} - 30 x + 350 = 0

x = - 70, x = 10

Solution steps

- 0.5 x^{2} - 30 x + 350 = 0

Multiply both sides by

10

- 5 x^{2} - 300 x + 3500 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 300 ) \pm ( - 300 ) ^{2} - 4 ( - 5 ) \cdot 3500}{2 ( - 5 )}

(- 300)^{2} - 4 (- 5) \cdot 3500 = 400

x_{1, 2} = \frac{- ( - 300 ) \pm 400}{2 ( - 5 )}

Separate the solutions

x_{1} = \frac{- ( - 300 ) + 400}{2 ( - 5 )}, x_{2} = \frac{- ( - 300 ) - 400}{2 ( - 5 )}

x = \frac{- ( - 300 ) + 400}{2 ( - 5 )} : - 70

x = \frac{- ( - 300 ) - 400}{2 ( - 5 )} : 10

The solutions to the quadratic equation are:

x = - 70, x = 10

2.5 x^{2} = 5 x + 50 - 8487.05 - 848.705 x

x^{2} - 39 = - 2 x + 9

3 x^{2} + 5 x + 2

8 z^{2} - 72 = 0

x, x^{2} + 2 x - 1 = 2
