TL;DR

Learn how to simplify algebraic expressions by combining like terms, using the distributive property, and multiplying/dividing monomials and binomials.

Transcript

in this video we're going to do a basic review of simplifying algebraic expressions so let's say if you have the expression 5x + 8 - 2x + 5 how can we simplify this expression to do so you need to combine like terms we can't add 5x and 8 we can't say that's 13x because these are not like terms 5x is similar to 2x because they carry the same variabl...

Questions & Answers

Q: How do you simplify algebraic expressions by combining like terms?

To combine like terms, add or subtract the coefficients of terms that have the same variable. Keep the variable the same and write the sum or difference of the coefficients.

Q: What is the distributive property and how is it used in simplifying expressions?

The distributive property allows you to multiply a number or variable to each term inside parentheses. This is done by multiplying the number or variable to each term separately.

Q: How do you multiply or divide monomials?

To multiply monomials, multiply the coefficients and add the exponents of like variables. To divide monomials, divide the coefficients and subtract the exponents of like variables.

Q: How do you multiply binomials using the FOIL method?

To multiply binomials, use the FOIL method: multiply the first terms, multiply the outer terms, multiply the inner terms, and multiply the last terms. Then, combine like terms.

Summary & Key Takeaways

• When simplifying expressions, combine like terms by performing operations on the coefficients and keeping the variable the same.

• The distributive property allows you to multiply a number or variable to each term inside parentheses.

• To multiply monomials, add the exponents of like variables. To divide monomials, subtract the exponents.

• When multiplying binomials, use the FOIL method (first, outer, inner, last) to multiply each term and then combine like terms.
