(15+11+6x2+1)-(13x2+2)
Combine like terms.
I will be happy to critique your work on this.
To combine like terms, we need to simplify the expression by adding or subtracting the terms that have the same variable with the same exponent.
Let's break down the given expression step by step:
Step 1: Simplify inside the parentheses.
Inside the parentheses, we have: (15 + 11 + 6x2 + 1) - (13x2 + 2)
Step 2: Perform the operations inside the parentheses.
15 + 11 = 26
6x2 = 12
13x2 = 26
After simplifying inside the parentheses, the expression becomes:
26 + 12 + 1 - 26 - 2
Step 3: Combine like terms using addition and subtraction.
26 + 12 + 1 - 26 - 2 can be rearranged as follows to make combining like terms easier:
(26 - 26) + 12 + 1 + (-2)
26 - 26 = 0, so we can remove it and write:
0 + 12 + 1 - 2
Now we can add and subtract:
0 + 12 = 12
12 + 1 = 13
13 - 2 = 11
Therefore, the simplified expression is 11.
