- x^{2} + 5 x + 30 = 0

x = - \frac{- 5 + 145}{2}, x = \frac{5 + 145}{2}

Decimal Notation

x = - 3.52079 \dots, x = 8.52079 \dots

Solution steps

- x^{2} + 5 x + 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 ( - 1 ) \cdot 30}{2 ( - 1 )}

5^{2} - 4 (- 1) \cdot 30 = 145

x_{1, 2} = \frac{- 5 \pm 145}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 5 + 145}{2 ( - 1 )}, x_{2} = \frac{- 5 - 145}{2 ( - 1 )}

x = \frac{- 5 + 145}{2 ( - 1 )} : - \frac{- 5 + 145}{2}

x = \frac{- 5 - 145}{2 ( - 1 )} : \frac{5 + 145}{2}

The solutions to the quadratic equation are:

x = - \frac{- 5 + 145}{2}, x = \frac{5 + 145}{2}

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

(x - 5) (x + 1) + 5 = 0

x^{2} = 1 0^{2} + 1 0^{2}

7 = - x^{2} - 9 x

x^{2} - \frac{3}{4} x - \frac{27}{64} = 0
