Find the difference and enter it in the box below. Enter exponents using the caret ( ^ ). For example, write 4x2 as 4x^2.  (2x7 + 4x4 - 2x + 3) - (4x4 - 2x3 + 3)

When you are subtracting polynomials from each other the first thing you want to do is distribute the negative sign throughout the second polynomial so that the expression would be:$$2x^7+4x^4-2x+3-4x^4+2x^3-3.$$
from there, you can simplify by grouping together the variables with the same degree (exponent) and combining their coefficients.

Thank you so much @Twis7ed I'm so confused with polynomials :-(

anonymous · Answer

So would I be combining the like terms? @Twis7ed

anonymous · Answer

Exactly, so 4x^4 - 4x^4 and 3 - 3. Everything else would stay the same
