Multiplying and Factoring Polynomial Expressions
Eureka Math Algebra 1 Module 4 Lesson 1 Objectives Students use the
distributive property to multiply a monomial by apolynomial and
understand that factoring reverses the multiplicationprocess.
Students use polynomial expressions as side lengths of polygons
andfind area by multiplying. Students recognize patterns and
formulate shortcuts for writing theexpanded form of binomials whose
expanded form is a perfect squareor the difference of perfect
squares. Standards: A-APR.A.1 a MP.4 You could add the two areas in
the previous question to get our answer.
If you find the area by multiplying the total length times total
width, that is using the distributive property. Main answer that
were looking for here is 3a(a+1)
Main answer that were looking for here is 3a(a+1).That is factoring
using the greatest common factor.GCF for short. 5a(2b+1) Factoring
the difference of two perfect squares reverses the process of
finding the product of the sum and difference of two terms.
