Question

$x^{2} /3-x/2=1/3$

Answer 1

mmc de 3 e 2 é 6

$2x^2-3x=2\\\\ 2x^2-3x-2=0\\\\ \Delta = b^2-4(a)(c)\\\\ \Delta = 9+16\\\\ \boxed{\Delta=25}$

$x = \frac{3+\ ou\ -\ 5}{4}\\\\ x^i = \frac{3+5}{4} = \frac{8}{4}=2\\\\ x^i^i = \frac{3-5}{4} = \frac{-2}{4}=-\frac{1}{2}\\\\\ \boxed{S(-\frac{1}{2},2)}$
