9 x^{2} + 15 x + 25 = 0

x = - \frac{5}{6} + i \frac{5 3}{6}, x = - \frac{5}{6} - i \frac{5 3}{6}

Solution steps

9 x^{2} + 15 x + 25 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 15 \pm 1 5 ^{2} - 4 \cdot 9 \cdot 25}{2 \cdot 9}

Simplify

1 5^{2} - 4 \cdot 9 \cdot 25 : 153 i

x_{1, 2} = \frac{- 15 \pm 15 3 i}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- 15 + 15 3 i}{2 \cdot 9}, x_{2} = \frac{- 15 - 15 3 i}{2 \cdot 9}

x = \frac{- 15 + 15 3 i}{2 \cdot 9} : - \frac{5}{6} + i \frac{5 3}{6}

x = \frac{- 15 - 15 3 i}{2 \cdot 9} : - \frac{5}{6} - i \frac{5 3}{6}

The solutions to the quadratic equation are:

x = - \frac{5}{6} + i \frac{5 3}{6}, x = - \frac{5}{6} - i \frac{5 3}{6}

x - 1 = 2

m^{2} = m + 20
