Select the correct answer from each drop-down menu.

When p2 - 4p is subtracted from p2 + p - 6, the result is. To get p - 9, subtract from this result.

p2 - 4p is subtracted from p2 + p - 6 can be written as:

(p² + p - 6) - (p² - 4p)

=p²+p-6-p²+4p

= (p²-p²) + (p+4p) - 6 Grouping the like terms.

=0+5p-6 Combining the like terms.

=5p-6

Now the question is to subtract p-9 from the above result 5p-6. So,

(5p-6) - (p-9)

=5p-6-p+9

= (5p-p) + (9-6)

=4p+3

Hence, the answer is 4p+3.
