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

x = - \frac{5 ( 21 - 3 )}{6}, x = \frac{5 ( 3 + 21 )}{6}

Decimal Notation

x = - 1.31881 \dots, x = 6.31881 \dots

Solution steps

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

Multiply both sides by

10

- 6 x^{2} + 30 x + 50 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 ( - 6 ) \cdot 50}{2 ( - 6 )}

3 0^{2} - 4 (- 6) \cdot 50 = 1021

x_{1, 2} = \frac{- 30 \pm 10 21}{2 ( - 6 )}

Separate the solutions

x_{1} = \frac{- 30 + 10 21}{2 ( - 6 )}, x_{2} = \frac{- 30 - 10 21}{2 ( - 6 )}

x = \frac{- 30 + 10 21}{2 ( - 6 )} : - \frac{5 ( 21 - 3 )}{6}

x = \frac{- 30 - 10 21}{2 ( - 6 )} : \frac{5 ( 3 + 21 )}{6}

The solutions to the quadratic equation are:

x = - \frac{5 ( 21 - 3 )}{6}, x = \frac{5 ( 3 + 21 )}{6}

- 4 k^{2} + 5 k = - 3 k - 4

\frac{4}{3} (x + 1)^{2} + 16 = 0

2 \cdot x^{2} - x - 2 = 0

x^{2} - 11 x - 46 = - 6 x + 4

x, x^{2} y - x^{2} + x y + 3 x - 2 = 0
