This week in math 10 we learned how to add and subtract polynomials and monomials this could be done by grouping up the like terms from both polynomials a like term is a term whose variables and exponents are the same and then simplifying the answer by combining the like terms or subtracting them based on the question. After that arrange the remaining terms in order of decreasing degree. An example of this would be in the equation (2×2 + 6x +5) + ( 3×2 – 2x – 1) we would start by grouping them which equals 2×2+3×2+6x-2x+5-1 we then add the like terms together this can be done by adding the amount of each like term variable together or just plain adding the constant terms together. This equals 5×2+4x+4 and this is the answer to the question. Another example of subtracting polynomials is (5×2+3x-2)-(x2+2x-4) we first start off doing the same as adding polynomials and group up the like terms this equals 5x+x2+3x+2x-2-4 then we subtract them instead of adding to get the answer in order of decreasing degree this equals (4x-x+2)
