x^{2} + 18 x + 70 = 0

x = - 9 + 11, x = - 9 - 11

Decimal Notation

x = - 5.68337 \dots, x = - 12.31662 \dots

Solution steps

x^{2} + 18 x + 70 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 18 \pm 1 8 ^{2} - 4 \cdot 1 \cdot 70}{2 \cdot 1}

1 8^{2} - 4 \cdot 1 \cdot 70 = 211

x_{1, 2} = \frac{- 18 \pm 2 11}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 18 + 2 11}{2 \cdot 1}, x_{2} = \frac{- 18 - 2 11}{2 \cdot 1}

x = \frac{- 18 + 2 11}{2 \cdot 1} : - 9 + 11

x = \frac{- 18 - 2 11}{2 \cdot 1} : - 9 - 11

The solutions to the quadratic equation are:

x = - 9 + 11, x = - 9 - 11

4 x^{2} - 40 x + 100

y^{2} - 12 y + 20

2 x^{2} + 7 x - 9

x^{2} = - 20 x - 99

x^{2} + 7 x y + 6 y^{2}
