Responde pela formula de Bhaskara.

Delta= b² - 4*a*c
Delta=(-5)² -4*1*6
Delta= 25-24
Delta=1

x= -b +- Raiz do Delta/2*a

x=-(-5) -+1/2

x'=2
x"=3

x²-5x+6=0
Δ= b²-4.a.c
  a=1,b=-5, c=6
Δ=(²-5)-4.1.6
Δ=25-24
Δ=1

  x=  \frac{-b+- √Δ}{2.a} =
  x1=+5+1/2.1= 6/2=3
  x2=+5 -1/2= 4/2=2

   S( X=2, X=3)
