Does FOIL only work for binomials?

Does FOIL only work for binomials?

The FOIL method is usually the quickest method for multiplying two binomials, but it works only for binomials. You can use the Distributive Property to find the product of any two polynomials. Another method that works for all polynomials is the Vertical Method.

Does FOIL work with trinomials?

Correct answer: To multiply trinomials, simply foil out your factored terms by multiplying each term in one trinomial to each term in the other trinomial.

Will FOIL work for every multiplication of polynomials?

Unfortunately, FOIL (an acronym for first, outer, inner and last) tends to be taught as THE way to multiply all polynomials, which is certainly not true. If students want to use FOIL, they need to be forewarned: You can ONLY use it for the specific case of multiplying two binomials.

Can you use FOIL method in quadratic equation?

In other words, we can use the FOIL method when polynomials or quadratic equation or expression is in its factored form. This example is a quadratic expression in its factored form. We perform FOIL by multiplying the terms in this order: First, Outside, Inside, Last.

Why cant the foil method be used for all polynomials?

Unfortunately, foil tends to be taught in earlier algebra courses as “the” way to multiply all polynomials, which is clearly not true. (As soon as either one of the polynomials has more than a “first” and “last” term in its parentheses, you’re hosed if you try to use Ffoil, because those terms won’t “fit”.)

Does foil method always work?

You should not rely on foil for general multiplication, and should not expect it to “work” for every multiplication, or even for most multiplications. If you only learn foil, you will not have learned all you need to know, and this will cause you problems later on down the road.

How do you turn an equation into FOIL?

Remember that when you FOIL, you multiply the first, outside, inside, and last terms together. Then you combine any like terms, which usually come from the multiplication of the outside and inside terms. For example, to factor x2 + 3x – 10, follow these steps: Check for the Greatest Common Factor (GCF) first.
