Question

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

7b + 3, -4b + 5, and -3b + 2

Answer 1

Wouldn’t it be b+10 ?

Answer 2

10

Explanation:

Let's write the given polynomials in vertical form and add them.

7b + 3

-4b + 5

-3b + 2

------------ [ 7b - 4b - 3b = 7b - 7b [-3b - 4b = -7b]

0b + 10 = 0b]

3 + 5 + 2 = 10

Therefore, the sum of the polynomial is 10.

Thank you.
