How to Multiply Binomials Using FOIL
Summary
TLDRThis instructional video demonstrates the FOIL method for multiplying binomials, using the example (x + 2)(x + 3). It explains each step of the acronym: multiplying the 'First' terms to get x squared, the 'Outer' terms to get 3x, the 'Inner' terms to get 2x, and the 'Last' terms to get 6. The video then shows the simplification process, combining like terms to result in the final expression x squared plus 5x plus 6.

Takeaways
- π The video is an educational tutorial on multiplying binomials using the FOIL method.
- π’ The FOIL acronym stands for First, Outer, Inner, Last, which are the steps to follow in the multiplication process.
- π The 'First' step involves multiplying the first terms of the binomials, which in the example is x * x, resulting in x squared.
- πΏ The 'Outer' step is multiplying the outer terms, which gives x * 3, equaling 3x.
- πΈ The 'Inner' step involves multiplying the inner terms, giving 2 * x, which simplifies to 2x.
- π The 'Last' step is multiplying the last terms of the binomials, resulting in 2 * 3, which equals 6.
- 𧩠After performing the FOIL steps, the equation must be simplified by combining like terms.
- π The x squared term remains as is, with no changes needed.
- π’ The x terms, 3x and 2x, are combined to form a single term, which is 5x.

Q & A
What is the FOIL method used for?
-The FOIL method is used for multiplying two binomials.
What does the 'F' in FOIL stand for?
-The 'F' in FOIL stands for 'First,' which means you multiply the first terms of each binomial together.
What is the result of multiplying the first terms in the example (x + 2)(x + 3)?
-The result of multiplying the first terms (x)(x) is x^2.
What does the 'O' in FOIL represent?
-The 'O' in FOIL represents 'Outer,' which means you multiply the outer terms of each binomial.
What is the product of the outer terms in the example (x + 2)(x + 3)?
-The product of the outer terms (x)(3) is 3x.
What does the 'I' in FOIL signify?
-The 'I' in FOIL signifies 'Inner,' which means you multiply the inner terms of each binomial.
What is the result of multiplying the inner terms in the example (x + 2)(x + 3)?
-The result of multiplying the inner terms (2)(x) is 2x.
What does the 'L' in FOIL stand for?
-The 'L' in FOIL stands for 'Last,' which means you multiply the last terms of each binomial.
What is the product of the last terms in the example (x + 2)(x + 3)?
-The product of the last terms (2)(3) is 6.
How do you simplify the expression obtained after applying the FOIL method to (x + 2)(x + 3)?
-After applying FOIL, you combine like terms: x^2 + 3x + 2x + 6 simplifies to x^2 + 5x + 6.
What is the final simplified form of the expression (x + 2)(x + 3) after using the FOIL method?
-The final simplified form of the expression is x^2 + 5x + 6.

Highlights
The video teaches the FOIL method for multiplying binomials.
The FOIL method acronym stands for First, Outer, Inner, Last terms.
First terms are multiplied together, e.g., x * x equals x squared.
Outer terms are multiplied next, resulting in 3x when multiplying x * 3.
Inner terms are then multiplied, giving 2x from 2 * x.
Last terms are multiplied to get 6 from 2 * 3.
The equation is simplified by combining like terms.
The x squared term remains as is.
The x terms, 3x and 2x, are combined to form 5x.
The number term 6 is kept as the constant.
The final simplified equation is x squared plus 5x plus 6.
The video encourages viewers to give a thumbs up if they find it useful.

Transcripts
this video will teach you how to
multiply binomials using the foil method
the example asks us to solve x + 2
multiplied by X plus 3 the F in foil
stands for first where we multiply the
first terms together that's x times X
and that will equal x squared the owin
foil asks you to multiply the outer
terms together this gives you x times 3
which equals 3x the I in foil asks you
to multiply the inner terms together
which gives us 2 times X and we can
simplify that to 2x and the L in foil
asks you to multiply the last term's
together 2 times 3 will equal 6
now we must simplify our equation we
look at x squared there is only one x
squared Turnham so we're going to write
our final answer as x squared there are
two x terms 3x plus 2x will equal
positive 5x and there is only one number
term so we will write that as positive 6
now our equation is x squared plus 5x
plus 6 and that will be our simplified
final answer if you found this video
