When p2 – 4p is subtracted from p2 p – 6, the result is

When dealing with the subtraction of polynomials, only the coefficients with similar variables can be subtracted. Assuming the two polynomials are p^2 + p - 6 and p^2 - 4p, the subtraction is shown below:
   
   p^2 + p - 6
-  p^2 - 4p

          +5p - 6

Therefore, the difference would be 5p - 6.
