Question

bhaskara grafico vertice da seguinte função.

A) x² - 5x + 6

B) Y = -X² - X+ 6

Answer 1

x²-5x+6=0

-b+-Vb²-4ac /2a 

5+-V25-4.1.6 /2.1

5+-V1 /2

5+-1 /2

x=5+1/2 =3
x'=5-1 /2 =2

Vx= -b/2a
Vx= 5/2

Vy= -Delta/4a
Vy= -1/4
----------------------------------------------------------------------
y=-x²-x+6

1+-V1-4.-1.6 /2.-1
1+-V25/-2
1+-5/ -2

x=1-5/-2 = 2
x'=1-5/ -2 =2

Vx= -1/2
Vy= -25/-4= 6,25
