2 x^{2} + 5 x + 6 = - 2 x

x = - \frac{3}{2}, x = - 2

Decimal

x = - 1.5, x = - 2

Solution steps

2 x^{2} + 5 x + 6 = - 2 x

Move

2 x

to the left side

2 x^{2} + 7 x + 6 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 2 \cdot 6}{2 \cdot 2}

7^{2} - 4 \cdot 2 \cdot 6 = 1

x_{1, 2} = \frac{- 7 \pm 1}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 7 + 1}{2 \cdot 2}, x_{2} = \frac{- 7 - 1}{2 \cdot 2}

x = \frac{- 7 + 1}{2 \cdot 2} : - \frac{3}{2}

x = \frac{- 7 - 1}{2 \cdot 2} : - 2

The solutions to the quadratic equation are:

x = - \frac{3}{2}, x = - 2

x, x^{2} + y^{2} = s^{2}

5 x^{2} - 25 x + 1 = 0

x^{2} - 11 x + 18 = 0

- 8 x^{2} + 3 = 0

x^{2} - 24 x = - 22 x + 24 - x^{2}
