Short Answer TypeClassify the following polynomials as monomials, binomials, trinomials. Which polynomials do not fit in any of these three categories?
x + y, 1000, x + x2+x3+x4, 7 + y +5x, 2y - 3y2+4y2 , 4z -15x2 , ab +bc + cd +da, p2q + pq2 , 2p + 2q.
Subtract 4a - 7ab + 3b + 12 from 12a - 9ab + 5b - 3
For subtraction we rearrange the terms such that the like terms are in the same column. Then we change the sign of the terms to be subtracted. Next we add the terms.
12a - 9ab + 5b - 3
4a - 7ab + 3b + 12
(-) (+) (-) (-)
