I did it once in middle schol but I don't remember the steps. It's where you enter a, b, c and then the answers come up. I'd really appreciate some help.

This is for my TI-81 but same principle:
This program solves equations of the form Ax^2+Bx+C=0 by using the quadratic formula.
:Disp "A" {Disp is in PRGM under I/O}
:Input A {Input is in PRGM under I/O}
:Disp "B"
:Input B
:Disp "C"
:Input C
:(B^2-4*A*C)-->D {The arrow is STO}
:If D<0 {If is in PRGM under CTL} {< is in TEST }
:Goto 1 {Goto is in PRGM under CTL}
:((-B+(D))/(2A))--->E {The "(D)" is the square root of D}{The - is the negative sign}
:((-B-(D))/(2A))----->F {The "(D)" is the square root of D, The second - is the subtraction sign}
:Disp "SOLUTIONS"
:Disp E
:Disp F
:End {End is in PRGM under CTL}
:Lbl 1 {Lbl is in PRGM under CTL}
:Disp "NO REAL SOLUTIONS"
:End

If you go to the Texas Instrument website, you can download a program directly into your calculator, provided you have the necessary cable.

My TI is a lot older than yours, but I suggest using trig rather than the quadratic as much as possible to find your solutions quickly.

Read the instructions and if they don't tell the answer take it back and tell them it is not working.
