5 x^{2} - 8 x - 30 = 0

x = \frac{4 + 166}{5}, x = \frac{4 - 166}{5}

Decimal Notation

x = 3.37681 \dots, x = - 1.77681 \dots

Solution steps

5 x^{2} - 8 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 5 ( - 30 )}{2 \cdot 5}

(- 8)^{2} - 4 \cdot 5 (- 30) = 2166

x_{1, 2} = \frac{- ( - 8 ) \pm 2 166}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 8 ) + 2 166}{2 \cdot 5}, x_{2} = \frac{- ( - 8 ) - 2 166}{2 \cdot 5}

x = \frac{- ( - 8 ) + 2 166}{2 \cdot 5} : \frac{4 + 166}{5}

x = \frac{- ( - 8 ) - 2 166}{2 \cdot 5} : \frac{4 - 166}{5}

The solutions to the quadratic equation are:

x = \frac{4 + 166}{5}, x = \frac{4 - 166}{5}

m^{2} + 4 m = - 3

3 (d - x)^{2} = x^{2}

12 x^{2} = 8 x - 8

u^{2} + 5 u + 6 = 0

15 x^{2} + 1107.91 x - 17739.55 = 0
