Simplify the expression <br><br> -2b - 6 + 3b - 2

Scilla [17]

Hello!

To do this we need to combine like terms, meaning combine the terms that have the same variables.

b is one variable that can be combined:

-2b - 6 + 3b - 2
b - 6 - 2

Now, combine the digits:

b - 8

Hope this helped!

Answer:

2a^2b(5a-3b)

Step-by-step explanation:

The GCF of 10a^3b and -6a^2b^2 is 2a^2b

So divide by that you will get

2a^2b(5a-3b)
