Question

Please help me and my son I am confused

Answer 1

Answer:

-13$p^{4}$ - $8p^{2}$ + 4p + 3

Step-by-step explanation:

I am having a little trouble reading the number.  I think 5 is the question number and not part of the problem.  I think this is the problem:

(4p - 6$p^{4}$ - 3) - (8$p^{2}$ + 7$p^{4}$ - 6)  You take the opposite of everything inside the second set of parentheses.  You can think of it as multiplying through by -1

4p - 6$p^{4}$ - 3 - 8$p^{2}$ - 7$p^{4}$ + 6  Now we combine like terms.  That is the numbers with the same variable p and the same power of p.

-13$p^{4}$ - 8$p^{2}$ + 4p + 3
