\frac{x ^{2} - 1}{2} - 11 x = 11

x = 23, x = - 1

Solution steps

\frac{x ^{2} - 1}{2} - 11 x = 11

Multiply both sides by

2

x^{2} - 1 - 22 x = 22

Move

22

to the left side

x^{2} - 22 x - 23 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 22 ) \pm ( - 22 ) ^{2} - 4 \cdot 1 \cdot ( - 23 )}{2 \cdot 1}

(- 22)^{2} - 4 \cdot 1 \cdot (- 23) = 24

x_{1, 2} = \frac{- ( - 22 ) \pm 24}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 22 ) + 24}{2 \cdot 1}, x_{2} = \frac{- ( - 22 ) - 24}{2 \cdot 1}

x = \frac{- ( - 22 ) + 24}{2 \cdot 1} : 23

x = \frac{- ( - 22 ) - 24}{2 \cdot 1} : - 1

The solutions to the quadratic equation are:

x = 23, x = - 1

\frac{x + 2}{- 5} > 10

(3 p)^{2}

\frac{( 8 0 ^{10} )}{( 8 0 ^{9} )}

x^{2} + x - 20 \leq 0

30 = - 4.9 t^{2} + 28 t + 40
