Catherine,
Afer you nvoke the Solver, you enter the followig equation (the Solver provides the single quotes):
'Y=SQ(3.5*X)*(1-X)*(1-3.5*X*(1-X))'
And then select th OK menu. The above equation defines two variables Y and X. The solver will display these variables. Enter 0 for Y and then enter a guess for X, followed by pressing the SOLVE menu command. Th SOLVER will display the solution for Y=0, i.e. the root.
The above equaion has a root of X=1.

I have an equation that I need to find the roots for. The equations looks like this:
x=3.5x(3.5x(1-x)[1-3.5x(1-x)]
Can it be entered into the HP48G? If so, how?
Multiplication must be explicit, and brackets (and braces, for that matter) are
not the same as parentheses. Try:
'x=3.5*x*(3.5*x*(1-x)*(1-3.5*x*(1-x)))'
Regards,
James
