- 2 x^{2} + 36 x + 138 = 0

x = 9 - 56, x = 9 + 56

Decimal Notation

x = - 3.24744 \dots, x = 21.24744 \dots

Solution steps

- 2 x^{2} + 36 x + 138 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 36 \pm 3 6 ^{2} - 4 ( - 2 ) \cdot 138}{2 ( - 2 )}

3 6^{2} - 4 (- 2) \cdot 138 = 206

x_{1, 2} = \frac{- 36 \pm 20 6}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 36 + 20 6}{2 ( - 2 )}, x_{2} = \frac{- 36 - 20 6}{2 ( - 2 )}

x = \frac{- 36 + 20 6}{2 ( - 2 )} : 9 - 56

x = \frac{- 36 - 20 6}{2 ( - 2 )} : 9 + 56

The solutions to the quadratic equation are:

x = 9 - 56, x = 9 + 56
