x^{2} + 20 x = - 70

x = - 10 + 30, x = - 10 - 30

Decimal Notation

x = - 4.52277 \dots, x = - 15.47722 \dots

Solution steps

x^{2} + 20 x = - 70

Move

70

to the left side

x^{2} + 20 x + 70 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 20 \pm 2 0 ^{2} - 4 \cdot 1 \cdot 70}{2 \cdot 1}

2 0^{2} - 4 \cdot 1 \cdot 70 = 230

x_{1, 2} = \frac{- 20 \pm 2 30}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 20 + 2 30}{2 \cdot 1}, x_{2} = \frac{- 20 - 2 30}{2 \cdot 1}

x = \frac{- 20 + 2 30}{2 \cdot 1} : - 10 + 30

x = \frac{- 20 - 2 30}{2 \cdot 1} : - 10 - 30

The solutions to the quadratic equation are:

x = - 10 + 30, x = - 10 - 30

y, x = - y^{2}

2 s^{2} + s^{2} = 5^{2}

(y + 5)^{2} = 9

1 + t^{2} = 2

x^{2} - 19 x - 39 = 0
