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

x = \frac{- 5 + 15}{2}, x = - \frac{5 + 15}{2}

Decimal Notation

x = - 0.56350 \dots, x = - 4.43649 \dots

Solution steps

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

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 2 \cdot 5}{2 \cdot 2}

1 0^{2} - 4 \cdot 2 \cdot 5 = 215

x_{1, 2} = \frac{- 10 \pm 2 15}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 10 + 2 15}{2 \cdot 2}, x_{2} = \frac{- 10 - 2 15}{2 \cdot 2}

x = \frac{- 10 + 2 15}{2 \cdot 2} : \frac{- 5 + 15}{2}

x = \frac{- 10 - 2 15}{2 \cdot 2} : - \frac{5 + 15}{2}

The solutions to the quadratic equation are:

x = \frac{- 5 + 15}{2}, x = - \frac{5 + 15}{2}

(\frac{x + 1}{2})^{2}

x^{2} - 5 = 4 x

(\frac{3 \cdot 8.314}{2}) (745 - 298)

14 x + 4 = 11 x + 22

9 x^{2} + 36 x = 0
