SOLUTION: hello, i am working on this math problem and i am not sure if i am solving it the right way or not. this is what i have done so far: {{{Y=(x-1)(x-5)}}} {{{x^2-x-5x+5}}} {{{x

Question 313091: hello, i am working on this math problem and i am not sure if i am solving it the right way or not. this is what i have done so far:

x=-2

23=Y
vertex=(-2,23)
Answer by ankor@dixie-net.com(22740) (Show Source): You can put this solution on YOUR website!

When you FOIL it will be
x^2 - 5x - x + 5, (essentially the same as you had)
then combining the middle terms

x=-2

y = 21
vertex=(-2,21)
This is not the vertex, just an ordered pair
:
To find the vertex, find the axis of symmetry, x = -b/(2a); b=-6; a=1
x =
x =
x = 3 is the axis of symmetry
Find the value of y using x=3
y = 3^2 - 6(3) + 5
y = 9 - 18 + 5
y = -4
:
The vertex: 3,-4
:
Looks like this:
