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

x = \frac{- 1 + 46}{3}, x = - \frac{1 + 46}{3}

Decimal Notation

x = 1.92744 \dots, x = - 2.59410 \dots

Solution steps

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

Solve with the quadratic formula

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

2^{2} - 4 \cdot 3 (- 15) = 246

x_{1, 2} = \frac{- 2 \pm 2 46}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 2 + 2 46}{2 \cdot 3}, x_{2} = \frac{- 2 - 2 46}{2 \cdot 3}

x = \frac{- 2 + 2 46}{2 \cdot 3} : \frac{- 1 + 46}{3}

x = \frac{- 2 - 2 46}{2 \cdot 3} : - \frac{1 + 46}{3}

The solutions to the quadratic equation are:

x = \frac{- 1 + 46}{3}, x = - \frac{1 + 46}{3}

3 x^{2} + 18 x - 81 = 0

x^{2} - 4 x - 45 = 0

2 x^{2} - 25 x + 75 = 0

6 w^{2} + w - 15 = 0

x^{2} + 0.18 x - 1 0^{- 14} = 0
