9 x^{2} + 3 x = - 2 x

x = 0, x = - \frac{5}{9}

Decimal Notation

x = 0, x = - 0.55555 \dots

Solution steps

9 x^{2} + 3 x = - 2 x

Move

2 x

to the left side

9 x^{2} + 5 x = 0

Solve with the quadratic formula

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

5^{2} - 4 \cdot 9 \cdot 0 = 5

x_{1, 2} = \frac{- 5 \pm 5}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- 5 + 5}{2 \cdot 9}, x_{2} = \frac{- 5 - 5}{2 \cdot 9}

x = \frac{- 5 + 5}{2 \cdot 9} : 0

x = \frac{- 5 - 5}{2 \cdot 9} : - \frac{5}{9}

The solutions to the quadratic equation are:

x = 0, x = - \frac{5}{9}

(9.81) (280) + \frac{1}{2} (5)^{2} = \frac{1}{2} x^{2}

(y - 1)^{2} = 1

u, 3 u^{2} - u - 3 = 0

x + x^{2} - 90 = 0

x^{2} + 17 x - 2 = 0
