When multiplying the following polynomial, 3a (6a2 - 3a + 4)

The second step would be to ~ coefficients and

When multiplying the polynomial 3a by the expression (6a^2 - 3a + 4), the second step would be to distribute the 3a to each term inside the parentheses.

Therefore, the second step is to multiply the coefficient, 3a, by each of the terms inside the parentheses:

3a * 6a^2 = 18a^3

3a * -3a = -9a^2

3a * 4 = 12a

So, the second step is to distribute and simplify the coefficients of each term.
