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

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

Decimal Notation

x = 1.66666 \dots, x = - 3

Solution steps

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

Solve with the quadratic formula

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

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

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

Separate the solutions

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

x = \frac{- 4 + 14}{2 \cdot 3} : \frac{5}{3}

x = \frac{- 4 - 14}{2 \cdot 3} : - 3

The solutions to the quadratic equation are:

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

3 (x - 3) (x + 3) = 2 (x - 1)

6 (2 - x) = 2 x + 4

- 2 q^{4} + 2 q^{3} + q^{2} - 1

a^{2} + 11 a + 30 = 0

\frac{2}{\frac{5}{3}}
