- 5 x^{2} + 5 x - 1.2 = 0

x = \frac{2}{5}, x = \frac{3}{5}

Decimal Notation

x = 0.4, x = 0.6

Solution steps

- 5 x^{2} + 5 x - 1.2 = 0

Multiply both sides by

10

- 50 x^{2} + 50 x - 12 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 50 \pm 5 0 ^{2} - 4 ( - 50 ) ( - 12 )}{2 ( - 50 )}

5 0^{2} - 4 (- 50) (- 12) = 10

x_{1, 2} = \frac{- 50 \pm 10}{2 ( - 50 )}

Separate the solutions

x_{1} = \frac{- 50 + 10}{2 ( - 50 )}, x_{2} = \frac{- 50 - 10}{2 ( - 50 )}

x = \frac{- 50 + 10}{2 ( - 50 )} : \frac{2}{5}

x = \frac{- 50 - 10}{2 ( - 50 )} : \frac{3}{5}

The solutions to the quadratic equation are:

x = \frac{2}{5}, x = \frac{3}{5}

- 5 x^{2} - 6 = - 4 x

6 t^{2} - 13 t = 15

x^{2} + (2 - 2 e^{2}) x + 2 = 0

v, p = \frac{m v ^{2}}{2}

2 x^{2} - 8 x + 16 = 38
