Best ResponseYou've already chosen the best response.0then combine like terms ..... a = e^2x 4a+6 = 0 a = 6/4 = 3/2 e^2x = 3/2 2x = ln(3/2) x = ln(3/2)/2

Best ResponseYou've already chosen the best response.0e^2x can be substituted for becasue it doesnt change in the problem; its an unknown that we determine; so to clean up the equation, make it = a and use 'a' instead. a 5a +6 =0 4a +6 = 0 4a = 6 a = 6/4 = 6/4 = 3/2

Best ResponseYou've already chosen the best response.0since e^2x = a ; we told it to ... e^2x = 3/2 we solve for x by using logarithmic properties.. ln(e^2x) = ln(3/2) 2x = ln(3/2) x = ln(3/2)  2

Best ResponseYou've already chosen the best response.0Its involved I guess.I would look into it.Thanks for your help.I appreciate it.

Best ResponseYou've already chosen the best response.0your welcome But I really think that this could have been a typo; which would make this part easier: a = e^x a^2 5a +6 = 0 (a6)(a+1) = 0 a = 6 and a = 1 e^x = a e^x = 6 ; x = ln(6) e^x = 1, which is impossible so disregard the 1 x = ln(6)
