- x^{2} - x + 9 = 0

x = - \frac{1 + 37}{2}, x = \frac{37 - 1}{2}

Decimal Notation

x = - 3.54138 \dots, x = 2.54138 \dots

Solution steps

- x^{2} - x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 ( - 1 ) \cdot 9}{2 ( - 1 )}

(- 1)^{2} - 4 (- 1) \cdot 9 = 37

x_{1, 2} = \frac{- ( - 1 ) \pm 37}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- ( - 1 ) + 37}{2 ( - 1 )}, x_{2} = \frac{- ( - 1 ) - 37}{2 ( - 1 )}

x = \frac{- ( - 1 ) + 37}{2 ( - 1 )} : - \frac{1 + 37}{2}

x = \frac{- ( - 1 ) - 37}{2 ( - 1 )} : \frac{37 - 1}{2}

The solutions to the quadratic equation are:

x = - \frac{1 + 37}{2}, x = \frac{37 - 1}{2}

x^{2} + 6 x + 8

0 < ∣ x - 2 ∣ < \frac{1}{2}

w^{2} - 2 w - 8 = 0

(x + 7)^{2}

7 x^{2} - 2 x = 0
