5 z^{2} + 18 z + 9 = 0

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

Decimal Notation

z = - 0.6, z = - 3

Solution steps

5 z^{2} + 18 z + 9 = 0

Solve with the quadratic formula

z_{1, 2} = \frac{- 18 \pm 1 8 ^{2} - 4 \cdot 5 \cdot 9}{2 \cdot 5}

1 8^{2} - 4 \cdot 5 \cdot 9 = 12

z_{1, 2} = \frac{- 18 \pm 12}{2 \cdot 5}

Separate the solutions

z_{1} = \frac{- 18 + 12}{2 \cdot 5}, z_{2} = \frac{- 18 - 12}{2 \cdot 5}

z = \frac{- 18 + 12}{2 \cdot 5} : - \frac{3}{5}

z = \frac{- 18 - 12}{2 \cdot 5} : - 3

The solutions to the quadratic equation are:

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

r^{2} + r - 2 = 0

- 18 < - 2 p \leq 12

5 x - 2 = - x - 20

3 x^{2} + 5 x = 3

3 x = 2 x + 2
