x^2+2x+x=0

Solution

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

Solution

x = 0, x = - 3

Solution steps

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

Refine

x^{2} + 3 x = 0

Solve with the quadratic formula

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

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

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

Separate the solutions

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

x = \frac{- 3 + 3}{2 \cdot 1} : 0

x = \frac{- 3 - 3}{2 \cdot 1} : - 3

The solutions to the quadratic equation are:

x = 0, x = - 3
