@mathstudent55 , @yahman

Answer 1

To multiply two polynomials together, the first step is to multiply each term of one polynomial by each term of the other polynomial.

Answer 2

yep i remember that

Answer 3

Start by multiplying 4s by each term of the second polynomial.
Then multiply 5 by each term of the second polynomial.
Then you need to combine like terms.

Answer 4

ok

Answer 5

28s3+19s2−8s+15

Answer 6

thanx @yahman

Answer 7

The first line is this:
\(28s^3 - 16s^2+ 12s + 35s^2 - 20s + 15\)

Answer 8

@yahman medal @mathstudent55 for me k

Answer 9

kk

Answer 10

XD

Answer 11

Now we combine like terms. Like terms have the same variables and exponents.
\(28s^3 + 19s^2 - 8s + 15\)

That is the final answer.
