(1/3x+5)(1/3x+5)
First thing to do, before you enter the value of the equation to your calculator multiply the first term((1/3x+5) from the second term(1/3x+5) to make your answer simplified.Then after that you will observed that your answer look like in this pattern AX2 +BX+C it means that the equation is in general form of quadratic equation. So, in your problem,we are looking for a value of X1 and X2,when you used your calculator in solving this problem, First On you calculator then look for the mode then press it after that look for the equation(EQN).Then from the side of the word EQN there is a corresponding number to press,from my calculator it is number 5..Then press it.After you press it, there is a equations choices,look for the equation AX2 +BX+C then press it(given number to press). Now,enter the value of A, B and C from your simplified answer. After pressing the value of A press = sign from your calculator same as B and C.After you enter all the value of A,B and C continuously press = sign from your calculator till you get the answer, the value of X1 and X2.

Where is the standard deviation
There isn't one. Press the "STAT VAR" button to bring up the statistics menu. "Sx" and "Sy" will give you the sample standard deviations, while "sigma x" and "sigma y" will give you the population standard deviations.
When I say "sigma" I mean the lower case Greek letter sigma, which looks like a lower-case "o" with a tail pointing to the right.
