Question

simplify the following expression by combining like terms: 4a + 1 + a + 3 ?a + \square

Explanation:

Step1: Group like terms

Group the terms with \(a\) and the constant terms: \((4a + a)+(1 + 3)\)

Step2: Combine like terms

For the \(a\)-terms: \(4a + a=5a\)
For the constant terms: \(1 + 3 = 4\)
So the simplified expression is \(5a+4\)

Answer:

\(5\) (for the coefficient of \(a\)) and \(4\) (for the constant term), so the filled expression is \(5a + 4\)
