Question

resolva a equação x²-5x+6=0

Answer 1

Explicação passo-a-passo:

a= 1 b= -5 c= 6

Delta=b^2-4•a•c

Delta=25-24

Delta=1

X'=-b+Vdelta / 2a

X'=5+1 / 2 = 6/2=3

X"=5-1 / 2 = 4/2=2

Answer 2

X²-5x+6=0 A= 1 B= -5 C= 6

-b+-√b²-4.a.c

___________

2.a

-(-5)+-√(-5)²-4.1.6

______________

2.1

+5+-√25-24

__________

2

5+-√1

_____

2

5+-1

____

2

X1 = (5+1) ÷ 2 = 3

X2 = (5-1) ÷ 2 = 2
