What is the only difference between adding and subtracting polynomials?

Sagot :

The basic difference between the addition and subtraction of polynomials has been explained below.

A polynomial is a mathematical expression containing two or more algebraic terms containing variables and their coefficients that involve operations such as addition, subtraction, and multiplication.

The basic difference between the addition and subtraction of polynomials is that since subtraction is the inverse of addition, all terms get the opposite sign upon subtraction. For example -

In addition - 2x²+3x+4 and 3x²+7x+9 are added and we get = 6x²+10x+13

In subtraction - The same polynomials are subtracted = -x²-7x-5

Henceforth, we see that the signs have changed to the opposite.
