4.08 Algebra 2
Transcript of 4.08 Algebra 2
Start with the un–simplified side, (x+y)2
The expression (x+y)2 can be re–written as (x+y)(x+y).
The expression (x+y)(x+y) can be multiplied using the Distributive Property. That results in x2+xy+xy+y2.
The expression x2+xy+xy+y2 can be simplified by adding the middle terms. This results in x2+2xy+y2. This proves that (x+y)2=x2+2xy+y2.
What can polynomial identities apply to beyond just polynomials?
Polynomial identities apply to more than just polynomials. Replacing the variables with numbers can help prove numerical relationships as well.
