Answer:
Using the distributive property, we may multiply each term in the first expression by each term in the second expression to multiply the expressions (5v2-v-7)(4v2+3v+3). Thus, we get:
5v^2(4v^2+3v+3) - v(4v^2+3v+3) - 7(4v^2+3v+3) We can simplify each of these products:
20v^4 + 15v^3 + 15v^2 - 4v^3 - 3v^2 - 3v - 28v^2 - 21v - 21
combine like terms:
20v^4 + 11v^3 - 16v^2 - 24v - 21
Because of this, the result of (5v2-v-7) and (4v2+3v+3) is 20v4 + 11v3 - 16v2 - 24v - 21.
