- 2 x^{2} + 7 x + 3 = 0

x = - \frac{- 7 + 73}{4}, x = \frac{7 + 73}{4}

Solution steps

- 2 x^{2} + 7 x + 3 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 ( - 2 ) \cdot 3}{2 ( - 2 )}

7^{2} - 4 (- 2) \cdot 3 = 73

x_{1, 2} = \frac{- 7 \pm 73}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 7 + 73}{2 ( - 2 )}, x_{2} = \frac{- 7 - 73}{2 ( - 2 )}

x = \frac{- 7 + 73}{2 ( - 2 )} : - \frac{- 7 + 73}{4}

x = \frac{- 7 - 73}{2 ( - 2 )} : \frac{7 + 73}{4}

The solutions to the quadratic equation are:

x = - \frac{- 7 + 73}{4}, x = \frac{7 + 73}{4}

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

- \frac{6}{7} - 1

80000 \cdot \frac{1}{( 1 + 0.06 ) ^{30}}

- 16 t^{2} - 8 t + 64

\frac{4}{11}
