- x^{2} + 14 x + 74 = 0

x = 7 - 123, x = 7 + 123

Decimal Notation

x = - 4.09053 \dots, x = 18.09053 \dots

Solution steps

- x^{2} + 14 x + 74 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 14 \pm 1 4 ^{2} - 4 ( - 1 ) \cdot 74}{2 ( - 1 )}

1 4^{2} - 4 (- 1) \cdot 74 = 2123

x_{1, 2} = \frac{- 14 \pm 2 123}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 14 + 2 123}{2 ( - 1 )}, x_{2} = \frac{- 14 - 2 123}{2 ( - 1 )}

x = \frac{- 14 + 2 123}{2 ( - 1 )} : 7 - 123

x = \frac{- 14 - 2 123}{2 ( - 1 )} : 7 + 123

The solutions to the quadratic equation are:

x = 7 - 123, x = 7 + 123

3 x^{2} + 5 x = 2

12 - 2 x - 3 x^{2}

b^{2} = 11 b

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

4 x^{2} - 13 + 3 = 0
