Follow the instructions step by step.
1> Press 'Mode' thrice.
2> The screen shows (1) EQN (2) MAT (3) VCT
3> Press 1
4> Screen shows ' Unknowns? 2 3' >
5> Press the right button (>) [ the big button at top middle ]
6> Screen shows 'Degree? 2 3'
7>Press 2 o 3 as you want.
8>Screen shows 'a?' 0
Now consider your eqn. It is in the form of ax^2 +bx + c = 0
or ax^3 + bx^2 + cx +d = 0
Considering x^2 - 34x + 1 = 0
a= 1 , b = -34, c = 1.
Screen shows 'a?' 0
9>Enter the value of a. (here it is 1, so enter 1 and press =)
10> Enter the value of b (here it is -34, enter it and press =)
11> Enter the value of c (here it is 1, enter it and press =)
12> BINGO! The two roots are displayed! At one time you can see only 1 root.
Screen shows x1 = 33.7056...
Press down arrow to see the other root.
x2 = 0.02943...
13> Give me 10 points!

I'm afraid that the only way to do it with that calculator is by plugging in the data from the quadratic formula... So all it does is number crunching for you, not really solve it...
