x^{2} + 10 x - 45 = 0

x = - 5 + 70, x = - 5 - 70

Decimal

x = 3.36660 \dots, x = - 13.36660 \dots

Solution steps

x^{2} + 10 x - 45 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 1 \cdot ( - 45 )}{2 \cdot 1}

1 0^{2} - 4 \cdot 1 \cdot (- 45) = 270

x_{1, 2} = \frac{- 10 \pm 2 70}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 10 + 2 70}{2 \cdot 1}, x_{2} = \frac{- 10 - 2 70}{2 \cdot 1}

x = \frac{- 10 + 2 70}{2 \cdot 1} : - 5 + 70

x = \frac{- 10 - 2 70}{2 \cdot 1} : - 5 - 70

The solutions to the quadratic equation are:

x = - 5 + 70, x = - 5 - 70

x^{2} + 6 x - 27 = 0

9^{2} + x^{2} = 1 7^{2}

x^{2} + 3 x + 5

x^{2} + 12 x

n^{2} - 2 n - 56 = 7
