Question

Resolva a equação do 2° grau incompleta

${x}^{2} - 6x = 0$

Answer 1

x² - 6x = 0
a= 1, b= -6, c= 0

∆= b² -4.a.c
∆= (-6)² -4.1.0
∆= 36

x= -b±√∆ /2.a

x'= 6+6/2.1
x'= 12/2
x'= 6

x"= 6-6/2
x"= 0/2
x"= 0

S= {6, 0}

Bons estudos! :)

Answer 2

x² - 6x= 0

x • (x - 6)= 0

x= 0

x - 6= 0

x= 6

S= ( 0 , 6)
