Question

Resolva conforme a formula de bhaskara 3xsobre 2-5×+2=0

Answer 1

Olá!

3x² – 5x + 2 = 0
a = 3
b = –5
c = 2

$x = \frac{ - b \: ± \: \sqrt{ {b}^{2} - 4ac } }{2a}$
$x = \frac{ - ( - 5) \: ± \: \sqrt{ { - 5}^{2} - 4.3.2 } }{2.3} \\ \: x = \frac{ 5 \: ± \: \sqrt{ 25 - 24} }{6} \\ x = \frac{ 5 \: ± \:1 }{6}$

x’ = 1
x" = 1/3
