x^{2} - 7 x = 8

x = 8, x = - 1

Solution steps

x^{2} - 7 x = 8

Move

8

to the left side

x^{2} - 7 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 1 \cdot ( - 8 )}{2 \cdot 1}

(- 7)^{2} - 4 \cdot 1 \cdot (- 8) = 9

x_{1, 2} = \frac{- ( - 7 ) \pm 9}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 9}{2 \cdot 1}, x_{2} = \frac{- ( - 7 ) - 9}{2 \cdot 1}

x = \frac{- ( - 7 ) + 9}{2 \cdot 1} : 8

x = \frac{- ( - 7 ) - 9}{2 \cdot 1} : - 1

The solutions to the quadratic equation are:

x = 8, x = - 1

2.25 (\frac{1}{100})

(x + 1)^{2} = 25

3 (v + 2) + v = 4 (v - 1) + 10

\frac{2}{5} t - \frac{6}{25} = \frac{3}{5} t + 3

\frac{2}{3} < x - \frac{1}{3} < 8
