hasil dari 3x²+5x-3

[tex]$\begin{align} 3x^2 + 5x - 3 &= 0 \\ 3x^2 + 5x&= 3 \\ \frac{3x^2 + 5x}{3} &= \frac{3}{3} \\ x^2 + \frac{5}{3}x &= 1 \\ x^2 + \frac{5}{3}x + \frac{25}{36} &= 1 + \frac{25}{36} \\ (x + \frac{5}{6} )^2&= \frac{61}{36} \\ x &= \frac{\sqrt{61} - 5}{6} ~~ or ~~ \frac{ -\sqrt{61} -5}{6} \end{align}[/tex]
