x^{2} + 10 x - 30 = 0

x = - 5 + 55, x = - 5 - 55

Decimal Notation

x = 2.41619 \dots, x = - 12.41619 \dots

Solution steps

x^{2} + 10 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 1 \cdot ( - 30 )}{2 \cdot 1}

1 0^{2} - 4 \cdot 1 \cdot (- 30) = 255

x_{1, 2} = \frac{- 10 \pm 2 55}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 10 + 2 55}{2 \cdot 1}, x_{2} = \frac{- 10 - 2 55}{2 \cdot 1}

x = \frac{- 10 + 2 55}{2 \cdot 1} : - 5 + 55

x = \frac{- 10 - 2 55}{2 \cdot 1} : - 5 - 55

The solutions to the quadratic equation are:

x = - 5 + 55, x = - 5 - 55

y, m = y^{2} - \frac{y ^{1}}{x ^{2}} - x^{1}

x, z^{2} + 4 y^{2} - 4 x^{2} = 0

3 r^{2} = 4 r - 1

z^{2} + 4 z + 1 = 0

x^{2} + 7 x - 9 = 0
