x^{2} + 6 x - 18 = 0

x = 3 (3 - 1), x = - 3 (1 + 3)

Decimal

x = 2.19615 \dots, x = - 8.19615 \dots

Solution steps

x^{2} + 6 x - 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot ( - 18 )}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot (- 18) = 63

x_{1, 2} = \frac{- 6 \pm 6 3}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 6 + 6 3}{2 \cdot 1}, x_{2} = \frac{- 6 - 6 3}{2 \cdot 1}

x = \frac{- 6 + 6 3}{2 \cdot 1} : 3 (3 - 1)

x = \frac{- 6 - 6 3}{2 \cdot 1} : - 3 (1 + 3)

The solutions to the quadratic equation are:

x = 3 (3 - 1), x = - 3 (1 + 3)

x^{2} + 8 x + 3

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

5 x^{2} + 9 = 14

x^{2} - 17 x - 60 = 0

(x + 3)^{2} = 81
