Question

-3x²-4x-2=-3 por favor quero com delta

Answer 1

-3x² -4x +1 = 0 * -1

3x² +4x -1 = 0

$\mathsf{\Delta=b^2-4ac}$

4² -4*-3

16 + 12

28 = 2² * 7

$\mathsf{x = \frac{-b \pm \sqrt{\Delta} }{2a}}$

-4 ± 2√7/(2*6)

-2 ± √7/3

$\boxed{{Resposta: \frac{-2 + \sqrt{7}}{3} ; \frac{-2 - \sqrt[]{7}}{3}}}$
