Question

1/4m²-1/3m+1/9 GENTE É URGENTE !!

Answer 1

$\frac{1}{4} m^{2} - \frac{1}{3}m+ \frac{1}{9}=0$

Multiplica tudo por 36 (mmc):
$9 m^{2}- 12m+4=0 \\ \\ \\ D= b^{2} -4ac \\ \\ D=(-12)^{2} -4*9*4 \\ \\ D=144-144 \\ \\ D=0 \\ \\ \\ x'= \frac{-b+ \sqrt{D} }{2a} \\ \\ x'= \frac{12+0 }{18} \\ \\ x'= \frac{2}{3} \\ \\ \\ x''= \frac{-b- \sqrt{D} }{2a} \\ \\ x''= \frac{12-0 }{18} \\ \\ x''= \frac{2}{3}$

D = Delta.
