15 x^{2} - x - 6 = 0

x = \frac{2}{3}, x = - \frac{3}{5}

Decimal Notation

x = 0.66666 \dots, x = - 0.6

Solution steps

15 x^{2} - x - 6 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 \cdot 15 ( - 6 )}{2 \cdot 15}

(- 1)^{2} - 4 \cdot 15 (- 6) = 19

x_{1, 2} = \frac{- ( - 1 ) \pm 19}{2 \cdot 15}

Separate the solutions

x_{1} = \frac{- ( - 1 ) + 19}{2 \cdot 15}, x_{2} = \frac{- ( - 1 ) - 19}{2 \cdot 15}

x = \frac{- ( - 1 ) + 19}{2 \cdot 15} : \frac{2}{3}

x = \frac{- ( - 1 ) - 19}{2 \cdot 15} : - \frac{3}{5}

The solutions to the quadratic equation are:

x = \frac{2}{3}, x = - \frac{3}{5}

- 3 (3 x + 15) - (10 + x) = 35

x^{2} - 1 = x^{2} - 1
