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

x = - \frac{1}{2}, x = 3

Decimal Notation

x = - 0.5, x = 3

Solution steps

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

Write in the standard form

a x^{2} + b x + c = 0

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

Solve with the quadratic formula

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

5^{2} - 4 (- 2) \cdot 3 = 7

x_{1, 2} = \frac{- 5 \pm 7}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 5 + 7}{2 ( - 2 )}, x_{2} = \frac{- 5 - 7}{2 ( - 2 )}

x = \frac{- 5 + 7}{2 ( - 2 )} : - \frac{1}{2}

x = \frac{- 5 - 7}{2 ( - 2 )} : 3

The solutions to the quadratic equation are:

x = - \frac{1}{2}, x = 3

6 x^{2} + 9 x + 2 = - 2 - 4 x - 3 x^{2}

6 p - 6 = p^{2}

2 x^{2} - 9 x - 2 = - 6

\frac{( 2 x \cdot ( x - 4 ) )}{3} + \frac{x}{5} = \frac{5}{3}

\frac{x ^{2}}{6} - \frac{24}{9} = 0
