Factoring. Factoring is the process of finding what to multiply together to get an expression. It is like “splitting” an expression into a multiplication of simpler expressions. The FOIL rule converts a product of two binomials into a sum of four (or fewer, if like terms are then combined) monomials.
What is the reverse of foil called?
(Recall that FOIL stands for First, Outer, Inner, Last, which is how we combine the terms.) The reverse process is called factoring.
Does foil mean opposite?

What is the difference between foiling and factoring?
When the FOIL method fails, you know for certain the given quadratic is prime. The FOIL method of factoring calls for you to follow the steps required to FOIL binomials, only backward. Remember that when you FOIL, you multiply the first, outside, inside, and last terms together.
How do you Unfoil something?
UnFOILing is a method for factoring a trinomial into two binomials. When you multiply two binomials together, you use the FOIL method, multiplying the First, then the Outer, then the Inner, and finally the Last terms of the two binomials into a trinomial.
Can foils be similar?
In literature, a foil is a character that has characteristics that oppose another character, usually the protagonist. The foil character may be completely opposite to the protagonist, or very similar with one key difference.

How do you factor quadratics?
Steps to factorize quadratic equation ax2 + bx + c = 0 using completeing the squares method are: Step 1: Divide both the sides of quadratic equation ax2 + bx + c = 0 by a. Now, the obtained equation is x2 + (b/a) x + c/a = 0. Step 2: Subtract c/a from both the sides of quadratic equation x2 + (b/a) x + c/a = 0.
What is General trinomial?
A general quadratic trinomial is a trinomial of the form ax2 + bx + c, where a, b, and c are real numbers.
