x^{2} - 18 x = - 77

x = 11, x = 7

Solution steps

x^{2} - 18 x = - 77

Move

77

to the left side

x^{2} - 18 x + 77 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 18 ) \pm ( - 18 ) ^{2} - 4 \cdot 1 \cdot 77}{2 \cdot 1}

(- 18)^{2} - 4 \cdot 1 \cdot 77 = 4

x_{1, 2} = \frac{- ( - 18 ) \pm 4}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 18 ) + 4}{2 \cdot 1}, x_{2} = \frac{- ( - 18 ) - 4}{2 \cdot 1}

x = \frac{- ( - 18 ) + 4}{2 \cdot 1} : 11

x = \frac{- ( - 18 ) - 4}{2 \cdot 1} : 7

The solutions to the quadratic equation are:

x = 11, x = 7

- 4.905 t^{2} + 2.78 t - 0.3 = 0

- 6 (n + 6) \geq 2 (n - 6)

\frac{2}{1 - i}

(3 x - 4)^{2} = 39
