5 x^{2} - 18 x = 8

x = 4, x = - \frac{2}{5}

Solution steps

5 x^{2} - 18 x = 8

Move

8

to the left side

5 x^{2} - 18 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 18 ) \pm ( - 18 ) ^{2} - 4 \cdot 5 ( - 8 )}{2 \cdot 5}

(- 18)^{2} - 4 \cdot 5 (- 8) = 22

x_{1, 2} = \frac{- ( - 18 ) \pm 22}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 18 ) + 22}{2 \cdot 5}, x_{2} = \frac{- ( - 18 ) - 22}{2 \cdot 5}

x = \frac{- ( - 18 ) + 22}{2 \cdot 5} : 4

x = \frac{- ( - 18 ) - 22}{2 \cdot 5} : - \frac{2}{5}

The solutions to the quadratic equation are:

x = 4, x = - \frac{2}{5}

9 \cdot (- \frac{7}{3})

- 5 x + 6 (4 x + 15) = 242

(- 5 x y^{2})^{2}

\frac{y ^{\frac{5}{13}}}{y ^{\frac{5}{26}}}
