Answer: 4x² + 4xy - 3y²
Concept:
When encountering questions that ask for simplifying algebraic expressions, using the FOIL method would be easier:
- <u>First</u>, which means multiplying the first terms together;
- <u>Outer</u>, which means that we multiply the outermost terms when the binomials are placed side by side;
- <u>Inner</u>, which means multiply the innermost terms together;
- <u>Last</u>, which means that we multiply the last term in each binomial together.
Solve:
<u>Given</u>
(2x - y) (2x + 3y)
<u>Expand parentheses and apply the FOIL method</u>
=4x² + 6xy - 2xy - 3y²
<u>Combine like terms</u>
=4x² + (6xy - 2xy) - 3y²
=
Hope this helps!! :)
Please let me know if you have any questions
You are using the distributive property so you will multiply all the numbers in the parentheses by 5. So the end expression would be 30m+20n-15p
