x^{2} - 9 x - 5 x - 2 = 0

x = 7 + 51, x = 7 - 51

Decimal Notation

x = 14.14142 \dots, x = - 0.14142 \dots

Solution steps

x^{2} - 9 x - 5 x - 2 = 0

Refine

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

Solve with the quadratic formula

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

(- 14)^{2} - 4 \cdot 1 \cdot (- 2) = 251

x_{1, 2} = \frac{- ( - 14 ) \pm 2 51}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 14 ) + 2 51}{2 \cdot 1}, x_{2} = \frac{- ( - 14 ) - 2 51}{2 \cdot 1}

x = \frac{- ( - 14 ) + 2 51}{2 \cdot 1} : 7 + 51

x = \frac{- ( - 14 ) - 2 51}{2 \cdot 1} : 7 - 51

The solutions to the quadratic equation are:

x = 7 + 51, x = 7 - 51

5 a^{2} - 11 a = 12

3 x - 7 \geq 14

12 + w < 19

\frac{5}{9} (9 d - 27) - 14 = 6

\frac{x}{- 2} > 4
