Why cant they include infinity symbol ? sometimes i feel my calculator is so dumb !
You cannot. The calculator does not have a Computer Algebra System or CAS. If you are trying to calculate an integral over an infine interval, you must try some high values to simulate infinity and find a value after which the value of the integral stops changing .

To convert a single result to decimal, press SD. To have all results come out in decimal, press SHIFT MODE 2 to select LineIO mode.

Unless I am failing to understand your problem, just combine like terms to get:
9x^2+2x+4 and then enter those coefficients into the quadratic solver.
That will get you the two answers -- both of them will be complex.
If you wanted to turn those two answers into factors (complex) of the original equation simply
change the signs on each and put an x in front.
Of course, the quadratic formula would also work.

Hi,
If you have mastered matrix manipulations on the TI calculators, it should be a breeze to learn the same on the Casios.
A. Define the matrix (Create it)
At the bottom of the screen you have 3 menus for Row and column manipulations. But those will have to wait for now.
Press [SHIFT][QUIT] to return to the list of matrices to create new ones
Operations on matrices
Once you have one matrix, you can do operations on it: Calculate the determinant (if matrix is square), calculate its inverse, transpose, augment it, fill it, etc..
Exemple : calculate the determinant of a matrix A (already defined).
Square of Matrix A
[OPTN][F2:MAT] (MAT) [Alpha] A ^2 [EXE]
Product of two compatible matrices MatAXMatB
[OPTN][F2:MAT] (MAT) [Alpha] A [* ) (MAT) [ALPHA] B [EXE]
Hope it helps.
Thank you for using FixYa.
