When i ask to solve it wont let me


If it is not accessible (grayed out) then the context is inappropriate. The reason could be the misuse of the verb solve. A lot of people confuse calculate with solve.
If you care to tell us what you were trying to do, exactly, maybe we can help.

Need instruction how to solve ploynomials/trinomials


You can do it two ways.
Graphically:
Open the graph utility, enter a function y1= expression(x) where expression(x) is the polynomial. Graph the function y1(x). Play with the window dimensions to display the interesting part of the graph. You can then see if there are any zeros (roots).
While the graph is displayed, press SHIFT F5 (G-Solv). Press F1:Root to look for a root. Read the value of the root at the bottom of the screen (to the left).

Solve utility
Open the QEquation solver, select F2:polynomial, or F3: solver.
The polynomial solve can solve polynomial equations up to degree 6.
The solve solve polynomial and any other type of non algebraic equations

Solving a linear equation from TI 83


Hi,
You have two ways to solve an equation (not just linear) in the TI83Plus
  1. The solve( command the syntax of which is solve( expr, var,guess, {lower_limit, upper_limit}). Here expr is the expression (without =0), var is the variable you solve for, guess is you estimate of the solution, lower_limit and upper_limit are the bounds of the domain where you are looking for a solution. Of course your guess must be between theses limits.
  2. The Interactive Solver.
The solve( command
  • The solve command is accessed through the catalog of commands [2nd][0] (CATALOG).
  • Press [LN] (S) to let the cursor jump to the first command that starts with s.
  • Scroll down to reach the solve( command.
  • Select it and press [ENTER]. The command echoes on main screen.
  • Enter the different arguments: expr, var, guess, etc.
  • Close the right parenthesis and press [ENTER].
  • Wait for the solution to be displayed.
The interactive solver

Press [MATH][0:Solver]. You see what is on the first picture (I entered K-0.5*V^2). Press [ENTER]. You see what is on the right picture.

5a3aa82.jpge9ed008.jpg
In the interactive solver you enter a value for all the parameters, constants, for all, save the entity you are solving for, here V. So you must clear the 0 to the right of the = sign after the V. when finished you press [ALPHA][ENTER] (SOLVE).
Here is what I get for the small exemple I chose.

Left -rt=0 shows that the root was found to within the calculator's tolerance.

Hope it helps.
Thank you for using FixYa.
