Answer:
Question:-
(a+b)^2=?
Solution:-
Extending the equation out by squaring the problem, we can get (a+b)(a+b). Then, following along with FOIL, if you are trying to lengthen the equation out to a trinomial, you would get a^2+2ab+b^2:
FOIL:
• First
• Outer
• Inner
• Last
So for (a+b)^2:
- First: a*a-a^2
- Outer: a*b=ab
- Inner: b*a=ab
- Last: b*b-b^2
Putting all that in order, we can get a^2+ab+ab+b^2, and by adding like terms, we can get a^2+2ab+b^2.
hope it's helpful :-)
