Simplify the expression by combining like terms:

Answer 1

2b² + 2b

Explanation:

b + 3b² + b - b²

= 3b² - b² + b + b

= 2b² + 2b

Answer 2

`\sf \: {2b}^(2) + 2b`

Explanation:

Given expression,

→ b + 3b² + b - b²

Let's simplify the expression,

→ b + 3b² + b - b²

→ (3b² - b²) + (b + b)

→ (2b²) + (2b)

→ 2b² + 2b

→ 2b(b + 1)

Hence, answer is 2b² + 2b.
