5a+7a²+3a
If you are combining like terms, you get 7a^2+8a.
5a+7a^2+3a= 8a+7a^2= a(8+7a)
To simplify the given expression 5a + 7a² + 3a, we can combine like terms. Like terms have the same variable(s) raised to the same power(s).
First, let's combine the terms that have the same variable (a) raised to the power of 1:
5a + 3a = 8a
Now, we are left with the term 7a², which cannot be combined with the other terms because it has a different power of a. So, the simplified expression becomes:
8a + 7a²
Therefore, 5a + 7a² + 3a simplifies to 8a + 7a².
