x^{2} + 10 x + 15 = 0

x = - 5 + 10, x = - 5 - 10

Decimal Notation

x = - 1.83772 \dots, x = - 8.16227 \dots

Solution steps

x^{2} + 10 x + 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 1 \cdot 15}{2 \cdot 1}

1 0^{2} - 4 \cdot 1 \cdot 15 = 210

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

Separate the solutions

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

x = \frac{- 10 + 2 10}{2 \cdot 1} : - 5 + 10

x = \frac{- 10 - 2 10}{2 \cdot 1} : - 5 - 10

The solutions to the quadratic equation are:

x = - 5 + 10, x = - 5 - 10

(3 + 2 i) (- 2 - i)

x - 0.4 x = 200
