Therefore, it can be expressed in the form of , where p and q are integers.

<span>Taking out the parentheses of expression
(5x2 + 3x + 4) − (2x2 + 5x − 1)
= 5x2 + 3x+ 4 -2x2 - 5x + 1
Grouping together the like terms and arranging the expression:
= 5x2 - 2x2 + 3x - 5x + 4 + 1
Combining the like terms:
= 3x2 - 2x + 5
Therefore,
A = 3
