x^{2} + 6 x - 12 = 0

x = - 3 + 21, x = - 3 - 21

Decimal Notation

x = 1.58257 \dots, x = - 7.58257 \dots

Solution steps

x^{2} + 6 x - 12 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot ( - 12 )}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot (- 12) = 221

x_{1, 2} = \frac{- 6 \pm 2 21}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 6 + 2 21}{2 \cdot 1}, x_{2} = \frac{- 6 - 2 21}{2 \cdot 1}

x = \frac{- 6 + 2 21}{2 \cdot 1} : - 3 + 21

x = \frac{- 6 - 2 21}{2 \cdot 1} : - 3 - 21

The solutions to the quadratic equation are:

x = - 3 + 21, x = - 3 - 21

x^{3} - 3^{3}

x^{3} - 7 x^{2} + 8 x + 16

4 \cdot \frac{π}{2}

10 x^{2} - 56 x y - 24 y^{2}

- 5 + x = 0
