Add polynomials using column method
a) $7x^2+8x+3xy, 9x^3+2xy-4$

Given:

Given polynomials are $7x^2+8x+3xy$ and $9x^3+2xy-4$.
To do:

We have to add the polynomials using the column method.
Solution:

The sum of $7x^2+8x+3xy$ and $9x^3+2xy-4$ using the column method is:

  $9x^3+ 0x^2+0x+2xy-4$

$+0x^3+7x^2+8x+3xy$ 
-------------------------------

 $9x^3+7x^2+8x+5xy-4$

-------------------------------
