Answer 1

convert it to a quadratic equation. No A, B , C

Type this function into calculater as a program

PRGM <enter> ->< enter> new-> <enter> put in name QUADSOLV

PROGRAM:QUADSOLV // Type in the following exactly as shown or actually find the function in the program menu

:ClrHome

:Input "A:",A

:Input "B:",B

:Input "C:",C

: B²-4*A*C → D (remark the → is the STO> button)

:If D<0

:Then

isp "NO REAL SOLUTION"

:Else

:If D=0

:Then

isp "X=",-B/(2*A) (remark you have to use the sign minus, not the operation minus!)

:Else

isp "X=",-B/(2*A)-√(D)/(2*A)

isp "OR"

isp "X=",-B/(2*A)+√(D)/(2*A)

:End

:End

If you have a interface cable to link your TI and computer, I can send you the file to be downloads in to that TI

I just run the TI on my TI-84+ so I'm am sure it will work on the TI-83 i.e. Backward compatible.

I will send to the file, you need a computer/calculator, as a attached via e mail.
