ANSWER:
Coefficient(s): 3 and 4
Exponent(s): 2
Term(s): 3x², 4x and 5
Explanation:
We have the following expression:

The term is something that is being added, a coefficient is a number that is multiplied by the variable and the exponent is an algebraic expression or a simple number that denotes the power to which another expression or another number (the base) must be raised.
Therefore, in this case:
• Coefficient(s): 3 and 4
,
• Exponent(s): 2
,
• Term(s): 3x², 4x and 5
