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

x = - 2, x = \frac{4}{3}

Decimal Notation

x = - 2, x = 1.33333 \dots

Solution steps

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

Solve with the quadratic formula

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

(- 2)^{2} - 4 (- 3) \cdot 8 = 10

x_{1, 2} = \frac{- ( - 2 ) \pm 10}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- ( - 2 ) + 10}{2 ( - 3 )}, x_{2} = \frac{- ( - 2 ) - 10}{2 ( - 3 )}

x = \frac{- ( - 2 ) + 10}{2 ( - 3 )} : - 2

x = \frac{- ( - 2 ) - 10}{2 ( - 3 )} : \frac{4}{3}

The solutions to the quadratic equation are:

x = - 2, x = \frac{4}{3}

x^{2} - 3 x = 7 x - 30

x^{2} + 16 x + 57 = 0

6 x^{2} + 18 x - 24 = 0

3 x^{2} + 2 a x + b = 0

3 x^{2} - 26 x + 40 = 0
