Question

Number of variables in 2x²​

Answer 1

Answer:

Note that the first column of the resultant matrix is [137,99]T[137,99]T.

On the one hand

[6122515][25bd]=[137991722]

[6251215][2b5d]=[137179922]

and on the other hand

[6122515][25bd]=[137996b+25d12b+25d].

[6251215][2b5d]=[1376b+25d9912b+25d].

We, then, have to solve the following system of linear equations:

6b+25d=17

6b+25d=17

12b+25d=22.

12b+25d=22.

This should not cause any problem:

The solutions are b=56b=56 and d=1225d=1225. These numbers give the second column of the given resultant matrix.
