- x^{2} + 17 x + 30 = 0

x = - \frac{- 17 + 409}{2}, x = \frac{17 + 409}{2}

Decimal Notation

x = - 1.61187 \dots, x = 18.61187 \dots

Solution steps

- x^{2} + 17 x + 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 17 \pm 1 7 ^{2} - 4 ( - 1 ) \cdot 30}{2 ( - 1 )}

1 7^{2} - 4 (- 1) \cdot 30 = 409

x_{1, 2} = \frac{- 17 \pm 409}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 17 + 409}{2 ( - 1 )}, x_{2} = \frac{- 17 - 409}{2 ( - 1 )}

x = \frac{- 17 + 409}{2 ( - 1 )} : - \frac{- 17 + 409}{2}

x = \frac{- 17 - 409}{2 ( - 1 )} : \frac{17 + 409}{2}

The solutions to the quadratic equation are:

x = - \frac{- 17 + 409}{2}, x = \frac{17 + 409}{2}

35 = - 2 x - 15

(x + 3)^{2} + 14 (x + 3) + 49

∣ x + 3 ∣ \geq 7

7 x^{2} - 6 = - 14

\frac{4}{9} \cdot 6
