x^{2} - 16 x = - 55

x = 11, x = 5

Solution steps

x^{2} - 16 x = - 55

Move

55

to the left side

x^{2} - 16 x + 55 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 16 ) \pm ( - 16 ) ^{2} - 4 \cdot 1 \cdot 55}{2 \cdot 1}

(- 16)^{2} - 4 \cdot 1 \cdot 55 = 6

x_{1, 2} = \frac{- ( - 16 ) \pm 6}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 16 ) + 6}{2 \cdot 1}, x_{2} = \frac{- ( - 16 ) - 6}{2 \cdot 1}

x = \frac{- ( - 16 ) + 6}{2 \cdot 1} : 11

x = \frac{- ( - 16 ) - 6}{2 \cdot 1} : 5

The solutions to the quadratic equation are:

x = 11, x = 5

6 x^{2} + 5 x = 4

25 r^{2} + 3 = 4

4 x^{2} - 169 = 0

a^{2} + 2 a - 5 = 0

3 x = \frac{1}{5} x^{2} + 10
