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

x = 1 + 15, x = 1 - 15

Decimal Notation

x = 4.87298 \dots, x = - 2.87298 \dots

Solution steps

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

Solve with the quadratic formula

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

(- 2)^{2} - 4 \cdot 1 \cdot (- 14) = 215

x_{1, 2} = \frac{- ( - 2 ) \pm 2 15}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 2 ) + 2 15}{2 \cdot 1}, x_{2} = \frac{- ( - 2 ) - 2 15}{2 \cdot 1}

x = \frac{- ( - 2 ) + 2 15}{2 \cdot 1} : 1 + 15

x = \frac{- ( - 2 ) - 2 15}{2 \cdot 1} : 1 - 15

The solutions to the quadratic equation are:

x = 1 + 15, x = 1 - 15

(\frac{1}{3})^{2} + 1

- 8 x + 1 < 41

4 (x - 2) + 15 = 3 (x + 4)

\frac{13 k ^{2}}{6 j ^{2} k ^{2}} \cdot 2 j k^{2}

\frac{- 5 x - 15}{2 x ^{2} + 5 x - 3}
