Here is the complete program. You may wish to copy it to the clipboard and paste it into your text editor. Now you can save it to a file and run it with SPIM.

## poly.asm -- complete program
##
## evaluate  5x^2 -12x + 97 
##
## Register Use:
##
## $10 base register, address of x
## $11 x
## $12 value of the polynomial
## $13 temporary

Of course, the program should be tested with a careful selection of values for x. A production quality program would document the upper and lower bounds for x.
