x^{2} + 18 x + 74 = 0

x = - 9 + 7, x = - 9 - 7

Decimal Notation

x = - 6.35424 \dots, x = - 11.64575 \dots

Solution steps

x^{2} + 18 x + 74 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 18 \pm 1 8 ^{2} - 4 \cdot 1 \cdot 74}{2 \cdot 1}

1 8^{2} - 4 \cdot 1 \cdot 74 = 27

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

Separate the solutions

x_{1} = \frac{- 18 + 2 7}{2 \cdot 1}, x_{2} = \frac{- 18 - 2 7}{2 \cdot 1}

x = \frac{- 18 + 2 7}{2 \cdot 1} : - 9 + 7

x = \frac{- 18 - 2 7}{2 \cdot 1} : - 9 - 7

The solutions to the quadratic equation are:

x = - 9 + 7, x = - 9 - 7
