Make sure you have two equations into the calculator. If, for instance, you were solving x^2 + 5x - 7 = 0, then your two equations would be: Y1=x^2+5x -7, and Y2=0. Then you would find the answers of x = 1.14005 and x = -6.14006.

@atwhotmail i wrote a program to actually solve any equation with ti-basic, just type in each side and it tells you x. it was easy

hey can you help me make a design or something i want to know how to make one pls reply THX^^

lol, for quadratic equations like the one that this guy just mentioned, you just put it into the quadratic formula. It will give you the imaginary solutions, too.

I wrote a program myself to do this (It's really easy)

(-b +or- sqrt(b*b-4*a*c))/(2*a)
