30 x^{2} - 11 x - 30 = 0

x = \frac{6}{5}, x = - \frac{5}{6}

Decimal Notation

x = 1.2, x = - 0.83333 \dots

Solution steps

30 x^{2} - 11 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 11 ) \pm ( - 11 ) ^{2} - 4 \cdot 30 ( - 30 )}{2 \cdot 30}

(- 11)^{2} - 4 \cdot 30 (- 30) = 61

x_{1, 2} = \frac{- ( - 11 ) \pm 61}{2 \cdot 30}

Separate the solutions

x_{1} = \frac{- ( - 11 ) + 61}{2 \cdot 30}, x_{2} = \frac{- ( - 11 ) - 61}{2 \cdot 30}

x = \frac{- ( - 11 ) + 61}{2 \cdot 30} : \frac{6}{5}

x = \frac{- ( - 11 ) - 61}{2 \cdot 30} : - \frac{5}{6}

The solutions to the quadratic equation are:

x = \frac{6}{5}, x = - \frac{5}{6}

x^{2} - (k + 1) x + 12 = 0

n^{2} = - 20 n - 100

f^{2} = 400

3 x^{2} + 6 x + 5

5 x^{2} + 10 x + 50 = 0
