Solution:

Given given expression to calculate is:

We have to add both the polynomials

Addition of two polynomials involves combining like terms present in the two polynomials

We have to add like terms

Like terms means "the terms having same variable and same exponent"

And we have to add the constants

Thus the polynomials are added
