Explanation:
To multiply the polynomials (8v - 5)(v + 7), we can use the distributive property:
(8v - 5)(v + 7) = 8v(v + 7) - 5(v + 7)
Now we can simplify by multiplying each term:
8v(v + 7) - 5(v + 7) = 8v^2 + 56v - 5v - 35
Finally, we can combine like terms to get the simplified expression:
8v^2 + 51v - 35
Therefore, (8v - 5)(v + 7) = 8v^2 + 51v - 35.
