Question

substract first polynomial from the second -6p³+7p²q²+pq; 7pq-5p³+9p²q²​

Answer 1

Answer:

$-p^3 - 2p ^2q^2-6pq$

Step-by-step explanation:

We have two polynomials and we are asked to subtract them, so let's breakdown the like terms in both of them and do as followed :

-6p^3 - 5p^3 = -p^3

7p^2q^2 - 9p^2q^2 = -2p^2q^2

pq - 7pq = -6pq

Now put these answers together :

-p^3 - 2p^2q^2 - 6pq

$-p^3 - 2p^2q^2 - 6pq$
