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.

Press [MODE][3][2]. In first column enter known x-coordinates (1 and 5), in second known y-coordinates (2 and 6). The solution you are looking for is in form Y=A+B*X where X=3. Your calculator computes A and B after you enter data. To calculate Y (which is equal to A+B*3 press [SHIFT][1][7][1][+][SHIFT][1][7][2][*][3][=]. The result should be 4.

If I helped you, please rate my answer :)

You can combine all the feet together 10+5+11=26 feet

Combine all the inches together -3-4-11=-18 inches=-2 ft + 6 inches

26 ft -2ft +6 inches =24 ft +6 in=24.5 ft

You can also multiply each inch -value by 1/12

10-3/12+5-4/12+11-11/12=10+5+11 -(3+4+11)/12=26-18/12, continue
