Объяснение:

Answer 2

To simplify the expression -5a(3a^2 + 4a), we can distribute the -5a to each term inside the parentheses:

-5a * 3a^2 = -15a^3 (multiplied the coefficients: -5 * 3 = -15, and added the exponents: a * a^2 = a^3)

-5a * 4a = -20a^2 (multiplied the coefficients: -5 * 4 = -20, and added the exponents: a * a = a^2)

Putting it together, the simplified expression is:

-15a^3 - 20a^2
