Question

Y = X*X - 6X + 8

Let A = the value when X is Zero
Let B = the largest value when Y = 0
Let C = the smaller value when Y = 0

THEN GO TO:
N27 26.A(3*C)(A+1)W82 33.A(2*B)C+1

Answer 1

what is this?
N27 26.A(3*C)(A+1)W82 33.A(2*B)C+1

Answer 2

Coordinates for a Geocache.

Answer 3

I can figure out the coordinates equation but the first part I don't know how to do.

Answer 4

I can help yo find A, B, and C.
For A plug in 0 for x.

For B and C, factor
\(x^2-6x+8=0\)
Find two numbers that multiply to 8 and add up to -6

Answer 5

I understand B and C, but I'm still confused about A. Could you explain that further please?

Answer 6

You substitute 0 for the x in the equation, then simplify to get y
Y=0² -6(0)+8

Answer 7

Y=8?

Answer 8

yes. so A = 8
What did you get for B and C?

Answer 9

B=-2
C=-4

Answer 10

Start with this
\(x^2-6x+8=0\)

Use the two numbers you found to factor
\((x-4)(x-2)=0\)

Set each of the factors equal to 0
\(x-4=0\) or \(x-2=0\)

Solve the equations for x
\(x=4\), \(x=2\)

So B = 4, C = 2

Answer 11

Oh that makes sense thank you very much!

Answer 12

you're welcome
