How do you write two binomials whose product is a difference of squares?
The two binomials can be written as (x - a)(x + a), for any constant a. Proof: Expand using FOIL: (x - a)(x + a) = x2 + xa - xa - a2 Group: (x - a)(x + a) = x2 - a2 x2 - a2 is a difference of squares. Thus, the product of (x - a) and (x + a) is a difference of squares.
How do you multiply two bionomials?
ONE WORD...FOIL. The FOIL method is a way to multiply binomials. "FOIL" is an acronym to remember a set of rules to perform this multiplication. To FOIL you multiply together all of the following: * F: Firsts * O: Outers * I: Inners * L: Lasts and then you add each of these products as demonstrated in the examples below. Let's take two arbitrary binomials. (x+a)(x+b) First: x^2 Outers: bx Inners: ax Last: ab So the product of these two binomials is x^2+bx+ax+ab Which we can simplify as x^2+x(a+b)+ab This is NOT the only way, another way is as below: (x+a)(x+b) Start with the x in x+a and multiply it by both terms in x+b so we have x^2+xb Now do the same with the a in x+a and we have ax+ab Add these all together and you have the same result as you did with the foil method. So why not just use foil? Why have two methods when one is plenty? GOOD QUESTION! The second method can be generalized to trinomials or any other types of polynomial multiplication and the FOIL method can't be.
You can find the product of any two binomials using what property?
distributive.

What is an acronym used to remember the steps needed to multiply two binomials?
You don't need any acronym; just multiply every monomial on the left with every monomial on the right. The same goes for multiplying a binomial with a trinomial, two trinomials, or in fact for multiplying any polynomial by any other polynomial.
Any proof of better gas mileage by wrapping the oxygen sensors in aluminum foil?
No, does not work.
Is X 8 a first degree binomial?
Any expression with form Ax+b where a and b are constants are first degree binomials.

Is foil made from carbon?
"Foil" can be any thin flexible sheets of metal- but the foil you use in the kitchen is made of aluminum. Carbon, being a nonmetal and generally rather brittle, would not make a good foil.
How do you make guitars out of aluminum foil?
You can make guitars out of aluminum foil in any way that you'd like. You can for example cut out a guitar shape in the foil and drawstrings on it with a marker.
Does foil make pork ribs turn green?
I have never seen foil turn any meat green.
