5 x^{2} + 30 x - 9 = 0

x = \frac{3 ( 30 - 5 )}{5}, x = - \frac{3 ( 5 + 30 )}{5}

Solution steps

5 x^{2} + 30 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 \cdot 5 ( - 9 )}{2 \cdot 5}

3 0^{2} - 4 \cdot 5 (- 9) = 630

x_{1, 2} = \frac{- 30 \pm 6 30}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- 30 + 6 30}{2 \cdot 5}, x_{2} = \frac{- 30 - 6 30}{2 \cdot 5}

x = \frac{- 30 + 6 30}{2 \cdot 5} : \frac{3 ( 30 - 5 )}{5}

x = \frac{- 30 - 6 30}{2 \cdot 5} : - \frac{3 ( 5 + 30 )}{5}

The solutions to the quadratic equation are:

x = \frac{3 ( 30 - 5 )}{5}, x = - \frac{3 ( 5 + 30 )}{5}

10 - 10 t = 5 t - 2 t^{2}

z, f = z^{2} - 5 z + 22 f (- 2)

- 3 x^{2} + 30 x - 72 = 0

(x - 3) 2 + 4 = - x^{2}

(x - 2) (3 x + 5) = x (x - 2)
