Answer 2

@amistre64 ?

Answer 3

complete the square on x, and solve for y ... that should get it into vertex form

Answer 4

how do you do that? can you take me through it step by step?

Answer 5

you should already have been exposed to this stuff. i just dont have the time at the moment to hash it out tho.

Answer 6

but i want to learn how to do it..

Answer 7

consider what a perfect square is ... (x+b)^2

expand it out and compare it to what you have already; then add a useful form of zero to complete the square.

its not that complicated, but it requires more focus than i can give to it at the moment.
