8 x^{2} - 13 x = 8

x = \frac{13 + 5 17}{16}, x = \frac{13 - 5 17}{16}

Solution steps

8 x^{2} - 13 x = 8

Move

8

to the left side

8 x^{2} - 13 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 8 ( - 8 )}{2 \cdot 8}

(- 13)^{2} - 4 \cdot 8 (- 8) = 517

x_{1, 2} = \frac{- ( - 13 ) \pm 5 17}{2 \cdot 8}

Separate the solutions

x_{1} = \frac{- ( - 13 ) + 5 17}{2 \cdot 8}, x_{2} = \frac{- ( - 13 ) - 5 17}{2 \cdot 8}

x = \frac{- ( - 13 ) + 5 17}{2 \cdot 8} : \frac{13 + 5 17}{16}

x = \frac{- ( - 13 ) - 5 17}{2 \cdot 8} : \frac{13 - 5 17}{16}

The solutions to the quadratic equation are:

x = \frac{13 + 5 17}{16}, x = \frac{13 - 5 17}{16}
