I need help in solving this subtraction (0.06x^30.07x^2+0.04x)(0.02x^3+0.07x^29)

Remove the parentheses. For the second set of parentheses, consider the  in front of it to be + 1 and distribute the 1 across all terms within that set of parentheses.
Rearrange terms so that they are in descending order.
Combine like terms.
