Step-by-step explanation:
1. You can apply the Elimination method:
- Mulitply the first equation by -2:
- Sum both equations and solve for y:
- Substitute the value obtained (y=-12) in one the original equations and then solve for x:
The sum of the polynomial is .
Given
In your notebook, set up the following addition using a vertical format and find the sum of the given polynomials.
<h3>Vertical Format:</h3>Write each polynomial below their like term and then combine it.
First expression:
Second Expression:
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;
Now, combine their coefficient and write the variable as same.
We can rearrange the term according to options.
Hence, the sum of the polynomial is .
