- 25 x^{2} - 30 x - 9 = 0

x = - \frac{3}{5}

Decimal Notation

x = - 0.6

Solution steps

- 25 x^{2} - 30 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 ( - 25 ) ( - 9 )}{2 ( - 25 )}

(- 30)^{2} - 4 (- 25) (- 9) = 0

x_{1, 2} = \frac{- ( - 30 ) \pm 0}{2 ( - 25 )}

x = \frac{- ( - 30 )}{2 ( - 25 )}

\frac{- ( - 30 )}{2 ( - 25 )} = - \frac{3}{5}

x = - \frac{3}{5}

The solution to the quadratic equation is:

x = - \frac{3}{5}

\frac{q ( q + 7 )}{7} - q = 4 - q^{2}

3 y^{2} + 9 y + 15

a x^{2} - (a + 2) x - 1 = 0

x, x^{2} y + x - y + 1 = 0

z^{2} - 11 z = 0
