A) X^2 - x + 6=0

B) m2 - 6m - 8 = 0​

Answer 1

Resposta:

A=  X^2 - x + 6=0

a=1 b=-1 c=6

delta=b²-4.a.c

delta =-1-4.1.6

delta=-1-24

delta=25

x=-b+ - raiz delta/2a

x'=1+5/2.1

x'=3

x''=1-5/2.1

x''=-2

B- m2 - 6m - 8 = 0​

a=1 b=-6 c=-8

delta=b²-4.a.c

delta=-36-4.1.(-8)

delta=4

x=-b+ - raiz delta/2a

x'=6+2/2.1

x'=4

x''=6-2/2.1

x''=2
