Question

simplify by combining like terms: 5a + 2b - 3a + 4; 8a + 2b + 4; 2a + 2b + 4; 8ab; 4ab + 4

Explanation:

Step1: Identify like terms for \(a\)

The terms with \(a\) are \(5a\) and \(-3a\). Combine them: \(5a - 3a=(5 - 3)a = 2a\)

Step2: Combine remaining terms

The term with \(b\) is \(2b\) (no other \(b\)-terms to combine), and the constant term is \(4\). So putting it all together: \(2a+2b + 4\)

Answer:

B. \(2a + 2b + 4\)
