Question

In your notebook, set up the following addition using a vertical format and find the sum of the given polynomials. 2mn 4n2 and 5m2 - 7mn 5 m2 5 mn - 4 n2 5 m2 - 14 mn - 4 n2 9 m2 9 mn - 4 n2 5 m2 - 5 mn 4 n2.

Answer 1

The sum of the polynomial is $\rm 5m^2+4n^2-5mn$.

Given

In your notebook, set up the following addition using a vertical format and find the sum of the given polynomials.

Vertical Format:

Write each polynomial below their like term and then combine it.

First expression: $\rm 2mn+4n^2$

Second Expression: $\rm 5m^2-7mn$

Now, we will add vertically. If the variable part of the term is the same then it would be like a term.

By using the vertical format the addition is;

$\rm 2mn+4n^2+0m^2$

$\rm 5m^2-7mn+0n^2$

Now, combine their coefficient and write the variable as same.

$\rm -5mn+4n^2+5m^2$

We can rearrange the term according to options.

$\rm 5m^2+4n^2-5mn$

Hence, the sum of the polynomial is $\rm 5m^2+4n^2-5mn$.
