PRECALC STUFF:
Completing the square:
*this is what they used to get the 81 in
that example
*be sure the equation is
in quadratic form (see
) then add that [ ]
to both sides of the
equation
TRICK: if theres no a in
front of the x then the
factors of c are

X=t1t=x+2
Y = t2 + 2
Y = (x + 2)2 + 2
Y = x2 + 2x +3
(then find the y values when given x)
