Question

Calcule a equação incompleta , com o método de bhaskara 3x²-x = 0 .

Answer 1

3x²-x =3x²-x+0=ax²+bx+c
a=3
b=-1
c=0

x'=[-b+√((b)²-4*a*c)]/2a

x''=[-b-√((b)²-4*a*c)]/2a

x'=[1+√(1-4*3*0)]/6=(1+1)/6=2/6=1/3

x'=[1-√(1-4*3*0)]/6=(1-1)/6=0/6=0

Answer 2

Olá!!!

3x² - x = 0

a = 3 , b = - 1 , c = 0

∆ = b² - 4ac
∆ = ( - 1 )² - 4 • 3 • 0
∆ = 1 - 0
∆ = 1

x = - b ± √∆ / 2a
x = - ( - 1 ) ± √1 / 2 • 3
x = 1 ± 1 / 6
x' = 1 + 1 / 6 = 2 / 6 (:2) = 1 / 3
x'' = 1 - 1 / 6 = 0 / 6 = 0

S = { 0 , 1 / 3 }

Espero ter ajudado...
