Question

How do you simplify `c^2 + 4d^2 +d^2 + 3d`?

Answer 1

All you have to do is combine like terms to simplify the expression.

Explanation:

You'll know when two terms are like terms when they have the same variable(s). In this case, we only have one pair of like terms: `4d^2` and `d^2`. Therefore, all we have to do is add the two terms together to get `5d^2`. We now have our simplified expression, `c^2+5d^2+3d`.
