Gimme the exact distance (fraction format) between
the vertex of x^2 - 18x + 45 = 0
and
the vertex of 2x^2 - 9x - 18 = 0
Now that you've warmed up:
gimme the distance between
the vertex of ax^2 + bx + c = 0
and
the vertex of Ax^2 + Bx + C = 0
in terms of a,b,c,A,B,C.
If yer asking yourself "has he just brushed
up on parabolas?", the answer is YES!
