2 x (x - 3) = 8 x^{2} - 11 x

x = 0, x = \frac{5}{6}

Decimal

x = 0, x = 0.83333 \dots

Solution steps

2 x (x - 3) = 8 x^{2} - 11 x

Expand

2 x (x - 3) : 2 x^{2} - 6 x

2 x^{2} - 6 x = 8 x^{2} - 11 x

Move

11 x

to the left side

2 x^{2} + 5 x = 8 x^{2}

Move

8 x^{2}

to the left side

- 6 x^{2} + 5 x = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 ( - 6 ) \cdot 0}{2 ( - 6 )}

5^{2} - 4 (- 6) \cdot 0 = 5

x_{1, 2} = \frac{- 5 \pm 5}{2 ( - 6 )}

Separate the solutions

x_{1} = \frac{- 5 + 5}{2 ( - 6 )}, x_{2} = \frac{- 5 - 5}{2 ( - 6 )}

x = \frac{- 5 + 5}{2 ( - 6 )} : 0

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

The solutions to the quadratic equation are:

x = 0, x = \frac{5}{6}

2 x^{2} - 17 x = - 30

- 6 y = - 24

\frac{\frac{2}{x + y}}{3}

∣ x + 3 ∣ < 8
