x^{2} + 10 x = - 7

x = - 5 + 32, x = - 5 - 32

Decimal Notation

x = - 0.75735 \dots, x = - 9.24264 \dots

Solution steps

x^{2} + 10 x = - 7

Move

7

to the left side

x^{2} + 10 x + 7 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 1 \cdot 7}{2 \cdot 1}

1 0^{2} - 4 \cdot 1 \cdot 7 = 62

x_{1, 2} = \frac{- 10 \pm 6 2}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 10 + 6 2}{2 \cdot 1}, x_{2} = \frac{- 10 - 6 2}{2 \cdot 1}

x = \frac{- 10 + 6 2}{2 \cdot 1} : - 5 + 32

x = \frac{- 10 - 6 2}{2 \cdot 1} : - 5 - 32

The solutions to the quadratic equation are:

x = - 5 + 32, x = - 5 - 32

n + 8 = - 10

3 x^{2} - 15

\frac{1}{28} + \frac{2}{28} + \frac{3}{28}

9 x^{2} - 12 x y + 4 y^{2}

6 x^{2} - 12 x - 48 = 0
