Depends on the kind of binomials.
Case 1:
If both binomials have different terms, then use the distribution property. Each term of one binomial will multiply both terms of the other binomial. After distribution, combine like terms, and it's done.
Case 2:
If both binomials have exactly the same terms, then work as in the 1st case, or use the formula for suaring a binomial, (a ± b)2 = a2 ± 2ab + b2.
Case 3:
If both binomials have terms that only differ in sign, then work as in the 1st case, or use the formula for the sum and the difference of the two terms, (a - b)(a + b) = a2 - b2.
It is only not needed if you know of another method. If FOIL is the only way you know to multiply two binomials, then it is definitely needed.
A product of binomials refers to the result of multiplying two binomial expressions, which are algebraic expressions containing two terms. For example, multiplying ((a + b)) and ((c + d)) results in a new expression obtained through the distributive property, leading to (ac + ad + bc + bd). This process is often visualized using the FOIL method (First, Outer, Inner, Last) for binomials. The resulting expression is a polynomial that may have more than two terms.
When multiplying numbers with exponents, you add the exponents.
To find the factor of 2 binomials
No, the product of two binomials is not always a trinomial; it is typically a trinomial when both binomials are of the form (ax + b)(cx + d) where at least one of the coefficients is non-zero. However, if either binomial includes a term that results in a cancellation or if both binomials are constants, the result could be a polynomial of a lower degree or a constant. For example, multiplying (x + 2)(x - 2) results in a difference of squares, yielding a binomial (x² - 4), not a trinomial.

to simplify the equation
It's the difference between multiplication and division. Multiplying binomials is combining them. Factoring polynomials is breaking them apart.
The foil method is a straightforward way to multiply two binomials quickly and accurately. It ensures all terms in the product are accounted for by multiplying each term in the first binomial by each term in the second binomial. This method is especially useful when dealing with simple polynomial multiplication.
Combining like terms.
When multiplying numbers with exponents, you add the exponents.
The same way that factoring a number is different from multiplying two factors. In general, it is much easier to multiply two factors together, than to find factors that give a certain product.
Use the "F-O-I-L" Method when multiplying two binomials. F-O-I-L stands for First, Outer, Inner, Last. Multiply the first terms together, then the outer terms, the inner terms, and the last terms.
