(5a2+2b2+3c2) + (a2−b2+c2)









To simplify the given expression, we can combine like terms. The expression is:

\[
(5a^2 + 2b^2 + 3c^2) + (a^2 - b^2 + c^2)
\]

First, let's remove the parentheses (since there are no subtraction signs in front of them, this step simply involves rewriting the terms):

\[
5a^2 + 2b^2 + 3c^2 + a^2 - b^2 + c^2
\]

Now, let's combine like terms:

1. Combine the \(a^2\) terms: \(5a^2 + a^2 = 6a^2\)
2. Combine the \(b^2\) terms: \(2b^2 - b^2 = b^2\)
3. Combine the \(c^2\) terms: \(3c^2 + c^2 = 4c^2\)

Thus, the simplified expression is:

\[
6a^2 + b^2 + 4c^2
\]

This is the result after combining like terms.
