Answer:
1.One way to simplify a polynomial is to combine the like terms if there are any. Two or more terms in a polynomial are like terms if they have the same variable (or variables) with the same exponent.
2.Step 1: Arrange each polynomial with the term with the highest degree first then in decreasing order of degree. Step 2: Group the like terms. Like terms are terms whose variables and exponents are the same. Step 3: Simplify by combining like terms.
3.To subtract Polynomials, first reverse the sign of each term we are subtracting (in other words turn "+" into "-", and "-" into "+"), then add as usual.
