9 z^{2} + 30 z + 25 = 0

z = - \frac{5}{3}

Decimal Notation

z = - 1.66666 \dots

Solution steps

9 z^{2} + 30 z + 25 = 0

Solve with the quadratic formula

z_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 \cdot 9 \cdot 25}{2 \cdot 9}

3 0^{2} - 4 \cdot 9 \cdot 25 = 0

z_{1, 2} = \frac{- 30 \pm 0}{2 \cdot 9}

z = \frac{- 30}{2 \cdot 9}

\frac{- 30}{2 \cdot 9} = - \frac{5}{3}

z = - \frac{5}{3}

The solution to the quadratic equation is:

z = - \frac{5}{3}

0 = - 16 t^{2} + 112 t + 128

y^{2} + 5 y - 24 = 0

2 (25 - 3 x^{2}) = 0

x^{2} = 56

x^{2} = 53
