help simply algebra but hard for me?

Question

subtract 2x-3x(2exponent)+5x(3exponent) from
-5x(3exponent) + 4x(2exponent)

The exponents are smaller numbers above the x's (powers).

Answer 1

subtract 2x-3x(2exponent)+5x(3exponent) from
-5x(3exponent) + 4x(2exponent)

I'll rewrite it as:
(-5x^3 + 4x^2) - (2x - 3x^2 + 5x^3)
Set it up as straight addition:

-5x^3 + 4x^2 - 2x + 3x^2 - 5x^3

Combine like terms:
-5x^3 - 5x^3 + 4x^2 + 3x^2 - 2x
-10x^3 + 7x^2 - 2x (solution!)

Answer 2

It appears like the problem should look like this:
(-5x^3 + 4x^2) - (2x - 3x^2 + 5x^3)
This subtracts the second part from the first part, which is what you said.

I'm not looking at your textbook, so it's hard for me to tell if this is the way you actually meant it.

You want to combine all like terms (all terms that have the same exponent on the x)

With exponents of 3, you have:
-5x^3 - 5x^3, which gives -10x^3. (Remember, the negative sign gets carried through all terms inside the second set of parentheses)

With exponents of 2, you have:
4x^2 - (-3x^2), and the two negatives cancel to become positive, and you have 7x^2 (again, the negative sign is carried through all terms inside the second set of parentheses).

With exponents of 1, you have:
-2x (The exponent is 1, even though you can't see it... there are no other terms with an exponent of 1, so you leave it as it is)

Therefore, the final answer is:
-2x + 7x^2 - 10x^3

Answer 3

It depends on how far out you are trying to solve the problem. I came up with 2x+7(2expo)-10x(3 expo)

Answer 4

it has been 12 years since I have even seen that, sorry I can't help.
