18 x^{2} + 8 x + 7 = 0

x = - \frac{2}{9} + i \frac{110}{18}, x = - \frac{2}{9} - i \frac{110}{18}

Solution steps

18 x^{2} + 8 x + 7 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 18 \cdot 7}{2 \cdot 18}

Simplify

8^{2} - 4 \cdot 18 \cdot 7 : 2110 i

x_{1, 2} = \frac{- 8 \pm 2 110 i}{2 \cdot 18}

Separate the solutions

x_{1} = \frac{- 8 + 2 110 i}{2 \cdot 18}, x_{2} = \frac{- 8 - 2 110 i}{2 \cdot 18}

x = \frac{- 8 + 2 110 i}{2 \cdot 18} : - \frac{2}{9} + i \frac{110}{18}

x = \frac{- 8 - 2 110 i}{2 \cdot 18} : - \frac{2}{9} - i \frac{110}{18}

The solutions to the quadratic equation are:

x = - \frac{2}{9} + i \frac{110}{18}, x = - \frac{2}{9} - i \frac{110}{18}

18 x^{2} = 3 x + 10

5 x^{2} + 7 x + 10 = 0

300 t (1 - t) = 0

3 x^{2} - 2 x = - 6

h^{2} = 7^{2} + 4^{2}
