15 x^{2} - 9 x - 6 = 0

x = 1, x = - \frac{2}{5}

Decimal Notation

x = 1, x = - 0.4

Solution steps

15 x^{2} - 9 x - 6 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 15 ( - 6 )}{2 \cdot 15}

(- 9)^{2} - 4 \cdot 15 (- 6) = 21

x_{1, 2} = \frac{- ( - 9 ) \pm 21}{2 \cdot 15}

Separate the solutions

x_{1} = \frac{- ( - 9 ) + 21}{2 \cdot 15}, x_{2} = \frac{- ( - 9 ) - 21}{2 \cdot 15}

x = \frac{- ( - 9 ) + 21}{2 \cdot 15} : 1

x = \frac{- ( - 9 ) - 21}{2 \cdot 15} : - \frac{2}{5}

The solutions to the quadratic equation are:

x = 1, x = - \frac{2}{5}

(2 x + 3) (x - 6) = 0

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

0 = 3 x^{2} - 12 x + 4

2 x^{2} + 4 x = 0

x, 12 z^{2} = 4 y^{2} - x^{2}
