6th Grade-Unit 4 Test Review

Front

What are like terms in algebra?

Back

Like terms are terms that have the same variable raised to the same power. For example, 2y and 4y are like terms, while 2y and 8x are not.

Front

How do you combine like terms?

Back

To combine like terms, you add or subtract the coefficients of the terms that are alike. For example, in 2y + 4y, you add the coefficients (2 + 4) to get 6y.

Front

What is the process of factoring in algebra?

Back

Factoring is the process of breaking down an expression into simpler components (factors) that, when multiplied together, give the original expression.

Front

What is the greatest common factor (GCF)?

Back

The greatest common factor is the largest factor that two or more numbers share. It is used in factoring expressions.

Front

How do you find the GCF of two numbers?

Back

To find the GCF, list the factors of each number and identify the largest factor that appears in both lists.

Front

What does it mean to simplify an expression?

Back

Simplifying an expression means to reduce it to its simplest form by combining like terms and performing any operations.

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by each term inside a parentheses.

Front

How do you apply the distributive property to simplify expressions?

Back

To apply the distributive property, multiply the term outside the parentheses by each term inside the parentheses and then combine like terms if possible.

Front

What is a polynomial?

Back

A polynomial is an algebraic expression that consists of variables, coefficients, and non-negative integer exponents, combined using addition, subtraction, and multiplication.

Front

What is the difference between a monomial, binomial, and trinomial?

Back

A monomial has one term, a binomial has two terms, and a trinomial has three terms.
