I need help in solving this subtraction (0.06x^3-0.07x^2+0.04x)-(0.02x^3+0.07x^2-9)
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.
