5 x^{2} + 7 x + 9 = 0

x = - \frac{7}{10} + i \frac{131}{10}, x = - \frac{7}{10} - i \frac{131}{10}

Solution steps

5 x^{2} + 7 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 5 \cdot 9}{2 \cdot 5}

Simplify

7^{2} - 4 \cdot 5 \cdot 9 : 131 i

x_{1, 2} = \frac{- 7 \pm 131 i}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- 7 + 131 i}{2 \cdot 5}, x_{2} = \frac{- 7 - 131 i}{2 \cdot 5}

x = \frac{- 7 + 131 i}{2 \cdot 5} : - \frac{7}{10} + i \frac{131}{10}

x = \frac{- 7 - 131 i}{2 \cdot 5} : - \frac{7}{10} - i \frac{131}{10}

The solutions to the quadratic equation are:

x = - \frac{7}{10} + i \frac{131}{10}, x = - \frac{7}{10} - i \frac{131}{10}

x^{2} + 14 x + 49

- 4 x^{2} - 4 x - 3 = 0

3 y^{2} + 2 = 0

4 x^{2} + 12 x - 44 = 0

0.51 = \frac{12.96 + 28.09 - c ^{2}}{38.16}
