The foil method in algebra is used to "multiply linear binomials."The FOIL method is used in elementary algebra as a guide for solving algebraic problems.
Yes FOIL method can be used with quadratic expressions and equations

The FOIL Method is a process used in algebra to multiply two binomials.f= first termso= outer termsi= inner termsl= last terms
Foil there are 2 different meanings of foil.... 1. An Aluminum foil to cover food, containers may be used in other things because it is a material. 2. To foil (Destroy or ruin) a plan
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.
If you mean (4x+7)(7x+6) then it is 28x^2 +24x+49x+42 using the FOIL method
To find the factor of 2 binomials
Synthetic method
you simply just use the FOIL method.:)
2(2) + 7x
