Question

Given polynomials 3xy,2xy,-7xy,5x²,8xy,-4y².Add the like terms and then unlike terms​

Answer 1

Step-by-step explanation:

terms which do not have the same literal coefficients raised to the same powers are calleddissimilar or unlike terms.

For example:

(i) 9p and 9q are unlike terms

(ii) x/3 and y/3 are unlike terms

Answer 2

Like terms:-

3xy, 2xy, -7xy, 8xy

Unlike terms:-

5x^2, -4y^2

3xy+2xy+(-7xy)+8xy

=6xy

Therefore, the answer is...

6xy+5x^2-4y^2
