2 x + x^{2} + 1 = 0

x = - 1

Solution steps

2 x + x^{2} + 1 = 0

Write in the standard form

a x^{2} + b x + c = 0

x^{2} + 2 x + 1 = 0

Solve with the quadratic formula

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

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

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

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

\frac{- 2}{2 \cdot 1} = - 1

x = - 1

The solution to the quadratic equation is:

x = - 1

x, x^{2} y^{2} - 4 x^{2} - 4 y^{2} = 0

2 x^{2} - 4 x - 3 = x

3 y^{2} + 6 y = 0

s^{2} - 2 s - 3 = 0

- x^{2} + 6 x - 5
