find the difference between the following polynomials -4xy^2 - 7xy + x - 4 and 8x^3 + x^2y + 6
Answers
Answer:
The word “polynomial” is derived from the words “poly” and “nomial”, which means many and terms respectively. A polynomial can have variables, constants and exponents, but an expression is not a polynomial if the variable is in the denominator, like 2/x + 3, 9xy-2, etc.
Like the numbers, they can undergo same type of operations. The operation of adding and subtracting polynomials is as easy as pie. You only need to be familiar with how to combine like terms and also the order of operations within the question. Before we can begin, let’s us recall, what like terms are.
In mathematics, like terms are terms that contain identical variables and exponents, regardless of their coefficients. An expression can be simplified by adding or subtracting depending on the signs before the terms.
