x^{2} - x - 9 = 0

x = \frac{1 + 37}{2}, x = \frac{1 - 37}{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 \cdot 1 \cdot ( - 9 )}{2 \cdot 1}

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

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

Separate the solutions

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

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

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

The solutions to the quadratic equation are:

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

- \frac{0.9 ( 10 )}{( 0.01 ( 10 ) ^{2} + 1 ) ^{2}}

4 x^{2} - 14 x - 8 = 0

x^{2} - 5 ∣ x ∣ + 6 = 0

- 5 n + 3 (6 + 7 n)

\frac{x - 5}{4} > 1
