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.

This is one of the most valuable tutoring channels on KZbin. No annoying music. No trying to be funny. The Pascal's triangle technique is fascinating! Thank you.

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.

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.

[@rojoryanjayb.389]

Same HAHAHA

[@Andresseus]

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.

[@DDchaos]

Dude, KZbin videos are so much easier than irl bc the teacher doesn’t go like “does anyone not get this?” And takes an hour before getting to the point

[@justagrumpystarfish2536]

isnt it in 9:48 4x square times 2x =8x cube? :

[@justagrumpystarfish2536]

and negative 12x times 2x = 24x square?

[@jackwilson4324]

[@hezakighamorgan9974]

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.

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
