3 x^{2} - 5 x = 8

x = \frac{8}{3}, x = - 1

Decimal Notation

x = 2.66666 \dots, x = - 1

Solution steps

3 x^{2} - 5 x = 8

Move

8

to the left side

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

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 5 ) \pm ( - 5 ) ^{2} - 4 \cdot 3 ( - 8 )}{2 \cdot 3}

(- 5)^{2} - 4 \cdot 3 (- 8) = 11

x_{1, 2} = \frac{- ( - 5 ) \pm 11}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 5 ) + 11}{2 \cdot 3}, x_{2} = \frac{- ( - 5 ) - 11}{2 \cdot 3}

x = \frac{- ( - 5 ) + 11}{2 \cdot 3} : \frac{8}{3}

x = \frac{- ( - 5 ) - 11}{2 \cdot 3} : - 1

The solutions to the quadratic equation are:

x = \frac{8}{3}, x = - 1

- 3 x^{2} + 21 x = 0

0 = x^{2} - 9 x + 8

y, 6 y^{2} d = 12

x, 8 x^{2} - k x + 2 = 0

4 x^{2} - 17 x + 3 = 0
