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

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

Solution steps

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

Solve with the quadratic formula

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

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

x_{1, 2} = \frac{- ( - 9 ) \pm 21}{2 \cdot 6}

Separate the solutions

x_{1} = \frac{- ( - 9 ) + 21}{2 \cdot 6}, x_{2} = \frac{- ( - 9 ) - 21}{2 \cdot 6}

x = \frac{- ( - 9 ) + 21}{2 \cdot 6} : \frac{5}{2}

x = \frac{- ( - 9 ) - 21}{2 \cdot 6} : - 1

The solutions to the quadratic equation are:

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

2 x (3 x - 5) = x

(x - 4)^{2} (x + 2) = (x + 2)^{2} (x - 4)

x (x^{2} + 2 x + 3) = x^{3} - 1

2 x^{2} = - 9 x - 10

15 m (m + 5) = 38 m - 20
