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

x = - 1, x = \frac{5}{3}

Decimal Notation

x = - 1, x = 1.66666 \dots

Solution steps

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

Solve with the quadratic formula

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

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

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

Separate the solutions

x_{1} = \frac{- 2 + 8}{2 ( - 3 )}, x_{2} = \frac{- 2 - 8}{2 ( - 3 )}

x = \frac{- 2 + 8}{2 ( - 3 )} : - 1

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

The solutions to the quadratic equation are:

x = - 1, x = \frac{5}{3}

2 x^{2} + 8 x + 5

2 x^{2} + 8 x + 3

x^{2} + 44 x = 4.16

- 21 x^{2} + 7 x = 0

6 n^{2} - 6 n + 3 = 4 n^{2}
