Question

Simplify the expression by combining like terms if possible. If not possible select already simplified. 4a^2+2a+4a^2-5

Answer 1

So the expression is:
`4 a^(2) + 2a + 4 a^(2) - 5`

You can combine like terms, which are terms that contain the same variables raised to the same power. That means you can combine the two
`4 a^(2)`.
`4 a^(2) + 4 a^(2) = 8 a^(2)` The other terms can't be combined.

Your final answer should be
`8 a^(2) +2a-5`.
