Simplify the product.

-3x (x^2 + 3x - 1)

distribute the -3x over the polynomial

i'd be really helpful step by step

multiply each term in the polynomial by -3x

the resulting polynomial is the answer

To simplify the product -3x(x^2 + 3x - 1), we need to distribute the -3x to each term inside the parentheses.

Start by multiplying -3x by x^2:
-3x * x^2 = -3x^3

Next, multiply -3x by 3x:
-3x * 3x = -9x^2

Then, multiply -3x by -1:
-3x * -1 = 3x

So the simplified product is:
-3x(x^2 + 3x - 1) = -3x^3 - 9x^2 + 3x
