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.

To subtract the expression (0.06x^3 - 0.07x^2 + 0.04x) from (0.02x^3 + 0.07x^2 - 9), you need to combine like terms.

Let's break down the steps:

Step 1: Group the like terms
(0.06x^3 - 0.07x^2 + 0.04x) - (0.02x^3 + 0.07x^2 - 9)

Step 2: Distribute the negative sign to each term inside the parentheses
0.06x^3 - 0.07x^2 + 0.04x - 0.02x^3 - 0.07x^2 + 9

Step 3: Combine the like terms
(0.06x^3 - 0.02x^3) + (-0.07x^2 - 0.07x^2) + (0.04x + 9)

Step 4: Simplify each term
0.04x^3 - 0.14x^2 + 9.04

Therefore, the subtraction of (0.06x^3 - 0.07x^2 + 0.04x) from (0.02x^3 + 0.07x^2 - 9) is simplified to 0.04x^3 - 0.14x^2 + 9.04.
