ADDITION OF POLYNOMIALS
(2r
^{4}
+ 3r
^{3}
- r
^{2}
+ 5r + 4) + (3r
^{4}
+ 4r
^{2}
-2r - 7)
(REMEMBER WE CAN ONLY ADD LIKE TERMS - 2r
^{4}
and 3r
^{4}
are like terms
because the variables and exponent are the same. 3r
^{3}
and 4r
^{2}
are unlike terms because their
exponents are different and hence cannot be combined. )
