**Steve**, Thursday, April 5, 2012 at 11:45amI'll do a couple. You try the rest, and come on back if you get stuck. Homework dumps not appreciated.

1)

y = x^2 + 3x - 10

y = (x^2 + 3x + (3/2)^2) - 10 - (3/2)^2

y = (x + 3/2)^2 - 49/4

6)

y = 3/4 (x^2 + 12x)

y = 3/4(x^2 + 12x + 36) - 3/4 * 36

y = 3/4 (x+6)^2 - 27

10)

y = -3(x-4)^2 + 1

y = -3(x^2 - 8x + 16) + 1

y = -3x^2 + 24x - 47
