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

x^{2} - 12 x + 36 = 0

x, 54 x + 64 \geq 49 x + 59

m, 4 - 2 m > 7 - 3 m

d, \frac{4}{5} d + 3 = - 2 - \frac{1}{5} d

6 - \frac{7}{6}
