x^{2} + 7 x = - 8

x = \frac{- 7 + 17}{2}, x = \frac{- 7 - 17}{2}

Decimal Notation

x = - 1.43844 \dots, x = - 5.56155 \dots

Solution steps

x^{2} + 7 x = - 8

Move

8

to the left side

x^{2} + 7 x + 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 1 \cdot 8}{2 \cdot 1}

7^{2} - 4 \cdot 1 \cdot 8 = 17

x_{1, 2} = \frac{- 7 \pm 17}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 7 + 17}{2 \cdot 1}, x_{2} = \frac{- 7 - 17}{2 \cdot 1}

x = \frac{- 7 + 17}{2 \cdot 1} : \frac{- 7 + 17}{2}

x = \frac{- 7 - 17}{2 \cdot 1} : \frac{- 7 - 17}{2}

The solutions to the quadratic equation are:

x = \frac{- 7 + 17}{2}, x = \frac{- 7 - 17}{2}

8 x + 3 = 8 x^{2}

x \cdot 0.45 + (- \frac{x ^{2}}{2 ( - 8.5 )}) = 50

x, - 36 (180 y^{4} - 36 y^{2} x + x^{2}) = 0

5 n^{2} = 125

10000 x + 20000 x^{2} - 21693.74 = 0
