Question

(2p^3+p^2-5p-2)by(2p+3)​

Answer 1

Step-by-step explanation:

you take the sum of products of each term in the first bracket with each term in the second. so with this example its would be:

=(2p3⋅3p)+(2p3⋅1)+(5p2⋅3p)+(5p2⋅1)+(−4⋅3p)+(−4⋅1)

This simplifies to:

=6p4+2p3+15p3+5p2−12p−4

=6p4+17p3+5p2−12p−4

Note: When multiplying variables with the same base you add their exponents

p3=p⋅p⋅p therefore p3⋅p=p⋅p⋅p⋅p=p4
