3x² + 5x - 2 = 0
D = b² - 4ac = 5² - 4×3×(-2) = 25 + 24 = 49
x1 = [latex] \frac{- 5 + \sqrt{49} }{6} [/latex] = [latex] \frac{2}{6} [/latex] = [latex] \frac{1}{3} [/latex]
x2 = [latex] \frac{ - 5 - \sqrt{49} }{6} [/latex] = [latex] \frac{-12}{6} = -2[/latex]
3(x - [latex] \frac{1}{3} [/latex])(x + 2) = 0
(x - [latex] \frac{1}{3} [/latex])(x + 2) = 0
x1 = [latex] \frac{1}{3} [/latex]
x2 = -2
