x^27x=11
Please Help!!!! Thanks.

x^27x=11
x^2  7x = 11
x^2  7x + 49/4 = 11 + 49/4
(x  7/2)^2 = 44/4 + 49/4
x  7/2 = ± √93/2
x = (7 ±√93)/2 
Thank you so much, but I was wondering:
x^27x=11
x^2  7x = 11
You have to divide by 1, wouldn't it be positive 7x. 
YOU ARE RIGHT!
good for you for catching that.
I am sure you can make the necessary changes.
(there is one small change) 
This is not a trigonometry question.
x^2 + 7x + (7/2)^2 = 11 + (7/2)^2
(x + 7/2)^2 = 23 1/4
x = 7/2 +/ sqrt(93)/2 
Thank you so much!!!!
Could you please help me with another type of trig math question. I greatly appreciate your help.
