5 x^{2} - 12 x - 9 = 0

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

Solution steps

5 x^{2} - 12 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 5 ( - 9 )}{2 \cdot 5}

(- 12)^{2} - 4 \cdot 5 (- 9) = 18

x_{1, 2} = \frac{- ( - 12 ) \pm 18}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 12 ) + 18}{2 \cdot 5}, x_{2} = \frac{- ( - 12 ) - 18}{2 \cdot 5}

x = \frac{- ( - 12 ) + 18}{2 \cdot 5} : 3

x = \frac{- ( - 12 ) - 18}{2 \cdot 5} : - \frac{3}{5}

The solutions to the quadratic equation are:

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

a^{2} - 3 a = 4

a^{2} - 3 a = 0

6 r^{2} + 9 r + 7 = 0

(x + 188) (x + 380) = 0

5 x^{2} - 120 = 5
