Example Question #55 : Quadratic Equations
Foil the two equations: 
Foiling means to take two equations and merge them into one. It's also the same as saying you want to multiply one equation with another, which is what we'll be doing.
Our two equations are 
Multiply the 
Multiply the 
Now multiply the 
Multiply the 
We won't multiply the second equation with the first one like we did above, as that would give us the same answers. Take all the answers you got from above and now string them together like so:
We're almost done, but we seem to be have more than one 
Since nothing else seems to have more than one of itself, we can now put the equation together. Make sure to go in order of highest power of 
Your answer is
Example Question #31 : Foil
On which of the following would one use the FOIL technique?
The FOIL technique is used to multiply or expand two binomials. None of the other expressions represent two binomials. The closest representation would be 
Example Question #372 : Algebra
Expand
One can use the FOIL method.
F:
O:
I:
L:
Adding them up, we get the polynomial 
Example Question #373 : Algebra
Evaluate
So FOIL works in this case
F:
O:
I:
L:
Example Question #374 : Algebra
Expand
This a case to FOIL
F:
O:
I:
L:
Example Question #375 : Algebra
Expand
Even though there is an 
F:
O:
I:
L:
Add the terms:
Example Question #376 : Algebra
Multiply 
The FOIL method works because there are two binomials.
F:
O:
I:
L:
Adding gives the polynomial
Example Question #931 : Ged Math
Multiply
We can use FOIL:
F: 
O: 
I: 
L: 
Example Question #32 : Foil
What is the degree of the polynomial represented as the product of the following two binomials?
A line.
A polynomial of degree 6.
A polynomial of degree 3.
A polynomial of degree 5.
A polynomial of degree 2
A polynomial of degree 5.
When the binomials are expanded, we get 
Example Question #39 : Foil
A rectangular prism-shaped box is given as having a width, 
First, we need to establish the dimensions of the box. We have the width, 
We need to find the area. The area of a rectangular prism is given as length times width times height. So, we can write
To set it up using FOIL, it can be arranged as 
Through FOIL, we get
