Complete the square by adding 6-1/4:
---> Remember to subtract 6-1/4 too so the value of the expression does not change.
----> convert to improper fractions so it's easier to deal with.
You know what, it follows "vertex-form" for a quadratic function:
--> VERTEX POINTS
Let's see the graph below:
---> see vertex (2-1/2,-81/4)
Let's see the x-intercepts:
By Quadratic Eqn:
See again the graph:
---> see the x-intercepts (-2,0) & (7,0).It's good!
