Do you know how to multiply them?

anonymous · Answer

a^2-b^2

anonymous · Answer

\you gotta multiply each term by the other

anonymous · Answer

$$(2+6)(3+8)$$ for ex for this you gotta do 2 times 3+2 times 8+ 6times 3+ 6 times 8

anonymous · Answer

Sorry, do you know whata perferct sqaure trinomial is?

anonymous · Answer

no

anonymous · Answer

Ok well its a trinomail that can be written as $$(a+b)^2=a^2+2ab+b^2$$
or $$(a-b)^2=a^2-2ab+b^2$$

anonymous · Answer

do you multiply two binomails together?

anonymous · Answer

know how to multiply*

anonymous · Answer

you add

anonymous · Answer

well ok if you have $$(a+b)(c+d)=ac+ad+bc+bd$$ fill it ion for your (a+b)(a+b)

anonymous · Answer

so its ab, ba

anonymous · Answer

(a+b)(a+b)=aa+ab+ab+bb=a^2+(2)ab+b^2

anonymous · Answer

does that fit a perfect square trinomial?

anonymous · Answer

I don't know what a perfect square trinomial is that's why I asked. is it?
