Answer:
7.1x + 6.6
Step-by-step explanation:
In order to subtract these two polynomials, you first have to change all the signs in the second parenthesis. Now you should have:
(2.1x + 2.6) - (5x + 4).
Next if you are subtracting vertically (it's easier this way, if you do) line up the like terms, like so⤵⤵⤵:
2.1x + 2.6
+ 5x + 4
7.1x + 6.6
Hope this helps you :)
