Question

1) DETERMINE AS RAÍZES DA EQUAÇÃO: 3x² -4x+1=0 obs: usar o discriminante =b²- 4ac ( a= 3 ) ( b= - 4 ) ( c = 1 ) x=[ -( b)]2a obs substituir na fórmula geral os valores de a, b e c.

Answer 1

$delta=(-4)^2 -4(3)\\delta=16-12\\delta=4\\\\x'= \frac{4 - 2}{2.3} \\\\x'=\frac{2}{6} :2 = \frac{1}{3} \\\\x''= \frac{4 +2}{2.3} \\x''= \frac{6}{6} \\x''= 1$
