When the expression 3x^2 - 8x + 7 is written in the form a(x+d)^2+e, where a, d, and e are constants, then what is the sum a+d+e?

3 ( x^2- 8/3x)         + 7          complet the square on 'x'

3 (x - 8/6)^2           + 7 - 3* 64/36

3 ( x- 4/3)^2         +  1 2/3                          Now you can add   a  d  e
