- 3 x^{2} - 4 x + 15 = 0

x = - 3, x = \frac{5}{3}

Decimal Notation

x = - 3, x = 1.66666 \dots

Solution steps

- 3 x^{2} - 4 x + 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 4 ) \pm ( - 4 ) ^{2} - 4 ( - 3 ) \cdot 15}{2 ( - 3 )}

(- 4)^{2} - 4 (- 3) \cdot 15 = 14

x_{1, 2} = \frac{- ( - 4 ) \pm 14}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- ( - 4 ) + 14}{2 ( - 3 )}, x_{2} = \frac{- ( - 4 ) - 14}{2 ( - 3 )}

x = \frac{- ( - 4 ) + 14}{2 ( - 3 )} : - 3

x = \frac{- ( - 4 ) - 14}{2 ( - 3 )} : \frac{5}{3}

The solutions to the quadratic equation are:

x = - 3, x = \frac{5}{3}
