Answer:To evaluate the expression (3x^2)(5x - 7), we need to distribute the 3x^2 to both terms inside the parentheses.

First, let's distribute 3x^2 to 5x:

(3x^2)(5x) = 15x^3

Next, let's distribute 3x^2 to -7:

(3x^2)(-7) = -21x^2

Now, we have two separate terms: 15x^3 and -21x^2.

Therefore, the simplified expression is:

15x^3 - 21x^2

In summary, when we evaluate (3x^2)(5x - 7), we distribute 3x^2 to each term inside the parentheses and simplify to get 15x^3 - 21x^2.

I think this might help
