Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Monomials

A monomial is a mathematical expression that consists of a single term, which can be a number, a variable, or a product of numbers and variables raised to non-negative integer powers. In the given question, '4x²' is a monomial, representing a coefficient (4) multiplied by a variable (x) raised to the power of 2.

Polynomials

A polynomial is an algebraic expression that consists of one or more terms, where each term is a product of a coefficient and variables raised to non-negative integer powers. The expression '3x + 2' is a polynomial with two terms, known as a binomial, which can be added or subtracted to form more complex expressions.

Distributive Property

The distributive property is a fundamental algebraic principle that states a(b + c) = ab + ac. This property allows us to multiply a monomial by each term in a polynomial. In the exercise, applying the distributive property means multiplying '4x²' by both '3x' and '2' to find the resulting expression.
