Foil Method Algebra, Binomials, Trinomials, Polynomials, Multiplication With Exponents

This algebra video tutorial focuses on the foil method. It explains how to multiply binomials, trinomials and polynomials together. It also includes foiling examples of binomials with exponents. In addition, this video goes over another technique known as the binomial theorem which goes along well with pascal's triangle. You can use the binomial expansion technique instead of the foil method whenever you have binomials with exponents to the 3rd power or higher.

If you don’t understand a certain thing, there’s probably another video he has where he’s explaining it.

[@Sceneyour]

And he is wrong at 9:50 so I guess you DONT understand. 4x2 is never 6.

​@weezo_ he can't even get this video right. Kahn is the best. They don't give you wrong answers. And he is wrong at 9:50...
. 4x2 is never 6.

[@User-je7gf]

@@Sceneyour No, he adds small mistakes like this on purpose so the person watching can catch the small mistakes themselves which makes them think about it and its great for learning

[@monicamir]

Study maths.
Go as deep as you can. And you can always go deeper.
Don't stop at calculus. Learn Algebra, symbolic logic, probability, combinatorics, set theory, Linear Algebra, Differential Equations.
Never stop. Never. Do it on your spare time.
Study music theory too.
All this will increase your cognitive capacity and make your brains sharper and less verbal.
This will be good for you.
Pray to Jesus that you may advance. Teach others. You learn more when you teach.
Best wishes.

12x*2x would equal 24x^2, not just a flat 24x. Also, 2 times 4 does not equal 6. A good refresher, good for the order of operation, but forgets some fundamental concepts throughout. Still helpful though.

[@fortifiedinchrist3739]

So understandable

[@andrescientos]

0:30 A "Square" appears over the "x" because "x" alone is not a shape, it's only a "line" with "1" dimension. So when you are multiplying 2 dimension, you write a ^2 to represent a 2 dimensional shape, like a square.

In short I guess the foil method can go from this:
(a+b)(c+d)
Which in foil
AC, BC, AD, BD
To even longer ones like
(2)(a+b+r+f+g+e)
Which in foils its
2a + 2b + 2r + 2f + 2g + 2e
If my mitosis is correct which I'm not sure bit
