Question

What is the answer to (12b^2+1)-(-8b^2)

Answer 1

Hey there!

Let's solve this problem step by step!

`(12b^(2) +1)-(-8b^(2) )`

Remove the parenthesis between the first sum.

`12b^(2) +1-(-8b^(2) )`

Work out the parenthesis that are left. Remember that multiplying a negative by a negative makes you end up with a positive outcome.

`12b^(2) +1+8b^(2)`

And finally collect the terms. We can only add the
`b^(2)`. We then find the following solution

`20b^(2) +1`

~Hope this helps you!

Answer 2

Use the formula
`c-(-d)=c+d`, where c and d are expressions.

Thus,

`(12b^2+1)-(-8b^2)=12b^2+1+8b^2=20b^2+1`

This is the final simplified expression.
