Question

What is the sum of −3x+6 and 7x−8?

Answer 1

Your sum will be "4x−2".

Answer 2

Step-by-step explanation: To add these polynomials,

we simply add (-3x + 6) + (7x - 8).

Notice that I used parenthses around the polynomials.

This is a good habit to get into even though

the parenthses will not affect the addition.

Next, we simply add the like terms.

-3x + 7x is 4x and 6 + -8 is -2 so we have 4x + -2 or 4x - 2.
