How Do You Subtract Polynomials Vertically?

Subtract the following two polynomials vertically.

Summary

  1. To find the additive inverse, just multiply the whole polynomial by -1
  2. We want to line up like terms over one another

Notes

    1. To find the additive inverse, just multiply the whole polynomial by -1
    2. This will switch the sign of every term in the polynomial
    1. We want to line up our polynomials so that like terms are above each other
    1. Fill in 0's where there are blank spots
    2. Remember, adding 0 doesn't change the value of the problem
    1. We already lined up all the like terms over each other, so now we can just add or subtract them
