Best ResponseYou've already chosen the best response.0heres what i got so far. : Using the quadratic formula: (Substitution) U = ((t^2)  7) ==> u^2  3u + 2 ==> Quadratic Formula ==> 3 + sqrt{9+8 ==> Answer that i got was : 3 (plus or minus) sqrt{ 17} divided by 2

Best ResponseYou've already chosen the best response.0May i ask, after the 3+ sqrt { 98} = 3+ sqrt {1}  2 so ==> it'd be 3+ 1 \2  31 \2?

Best ResponseYou've already chosen the best response.1the final answer is to solve for t....not u :) final answers should be: + 2sqrt(2) and +3
