Answer 5

ok ( x + 2 / 3 ) ^ 2 - 3

Answer 6

...... good job...... but my plan backfired :)

Answer 7

(x + 2/3 )^2 - 3 ??

Answer 8

I assume it is x + (2/3), but i will give solution for both.

[x + (2/3)]^2 - 3 = [x^2 + (4/3)x + (4/9)] - 3 = x^2 +(4/3)x - (23/9)

[(x+2)/3]^2 - 3 = [(x+2)^2 / 9] - 3 = (x^2 + 4x + 4)/9 - (27/9)
= (x^2 + 4x -23)/9
