roots

x^{2} + 2 x - 1

x = - 1 + 2, x = - 1 - 2

Solution steps

x^{2} + 2 x - 1

The roots are the intercepts with the x-axis

(y = 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) = 22

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

Separate the solutions

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

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

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

The solutions to the quadratic equation are:

x = - 1 + 2, x = - 1 - 2

x^{2} + 3 = 7

x, z = x^{2} + 4 y^{2}

x^{2} + 10 x + 1 = 24

y, x^{2} + y^{2} + 3 x + y + 10 = 0

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