3x^2+18x=0

Solution

3 x^{2} + 18 x = 0

Solution

x = 0, x = - 6

Solution steps

3 x^{2} + 18 x = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 18 \pm 1 8 ^{2} - 4 \cdot 3 \cdot 0}{2 \cdot 3}

1 8^{2} - 4 \cdot 3 \cdot 0 = 18

x_{1, 2} = \frac{- 18 \pm 18}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 18 + 18}{2 \cdot 3}, x_{2} = \frac{- 18 - 18}{2 \cdot 3}

x = \frac{- 18 + 18}{2 \cdot 3} : 0

x = \frac{- 18 - 18}{2 \cdot 3} : - 6

The solutions to the quadratic equation are:

x = 0, x = - 6
