-6 / 2 = -3 so
x^2 - 6x + 8 is
(x - 3)^2 -9 + 8
= (x - 3)^2 - 1
the vertex is at (3,-1)
Answer:
2,3,6
Step-by-step explanation:
those are the only positive factors in there
You start by adding 4 to both sides, isolating the X. then you have your answer X < 3
Answer:
x = -1 or 5
Step-by-step explanation:
From the expression (x +1) (x - 5)
We’re to solve for x.
Therefore,
x + 1 = 0
Subtract one from both sides
x + 1 - 1 = 0 - 1
x = -1
x - 5 = 0
Add five to both sides
x - 5 + 5 = 0 + 5
x = 5
