- x^{2} + 8 x - 4 = 0

x = 2 (2 - 3), x = 2 (2 + 3)

Solution steps

- x^{2} + 8 x - 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 ( - 1 ) ( - 4 )}{2 ( - 1 )}

8^{2} - 4 (- 1) (- 4) = 43

x_{1, 2} = \frac{- 8 \pm 4 3}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 8 + 4 3}{2 ( - 1 )}, x_{2} = \frac{- 8 - 4 3}{2 ( - 1 )}

x = \frac{- 8 + 4 3}{2 ( - 1 )} : 2 (2 - 3)

x = \frac{- 8 - 4 3}{2 ( - 1 )} : 2 (2 + 3)

The solutions to the quadratic equation are:

x = 2 (2 - 3), x = 2 (2 + 3)

- 3 x^{2} - 48 x + 543 = 0

0.3 \cdot 0.3
