- 0.012 x^{2} - 8 x + 430 = 0

x = - \frac{2150}{3}, x = 50

Decimal Notation

x = - 716.66666 \dots, x = 50

Solution steps

- 0.012 x^{2} - 8 x + 430 = 0

Multiply both sides by

1000

- 12 x^{2} - 8000 x + 430000 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 8000 ) \pm ( - 8000 ) ^{2} - 4 ( - 12 ) \cdot 430000}{2 ( - 12 )}

(- 8000)^{2} - 4 (- 12) \cdot 430000 = 9200

x_{1, 2} = \frac{- ( - 8000 ) \pm 9200}{2 ( - 12 )}

Separate the solutions

x_{1} = \frac{- ( - 8000 ) + 9200}{2 ( - 12 )}, x_{2} = \frac{- ( - 8000 ) - 9200}{2 ( - 12 )}

x = \frac{- ( - 8000 ) + 9200}{2 ( - 12 )} : - \frac{2150}{3}

x = \frac{- ( - 8000 ) - 9200}{2 ( - 12 )} : 50

The solutions to the quadratic equation are:

x = - \frac{2150}{3}, x = 50

z^{2} + 4 z + 16 = 0

x^{2} - 16 x + 64 = 12

7 x^{2} + 4 x + 4 = 8 x + 2

x^{2} + 12 x - 20 = 8

55 x^{2} = 34 x + 21
