- 3 x^{2} + 5 x + 8 = 0

x = - 1, x = \frac{8}{3}

Decimal Notation

x = - 1, x = 2.66666 \dots

Solution steps

- 3 x^{2} + 5 x + 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 ( - 3 ) \cdot 8}{2 ( - 3 )}

5^{2} - 4 (- 3) \cdot 8 = 11

x_{1, 2} = \frac{- 5 \pm 11}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- 5 + 11}{2 ( - 3 )}, x_{2} = \frac{- 5 - 11}{2 ( - 3 )}

x = \frac{- 5 + 11}{2 ( - 3 )} : - 1

x = \frac{- 5 - 11}{2 ( - 3 )} : \frac{8}{3}

The solutions to the quadratic equation are:

x = - 1, x = \frac{8}{3}

x^{2} + 4 x + 29

2 n^{2} + 9 n + 10 = 0

x^{2} - 8 x = 0

q^{2} = - 9

(x + 1)^{2} = \frac{x}{2} (5 x + 6) - (2 x^{2} + 1)
