02-FOIL of binomials and trinomials

admin — Fri, 24 Aug 2012 01:03:06 +0000

FOIL On Bigger Problems (trinomials) These problems have more terms than basic FOIL, but the same principals apply. One: everything in the first parentheses has to get multiplied by everything in the other parentheses. Two: don't forget anyone! Once again, my patented "draw rainbows everywhere" technique should make it easier to remember. NOTE: Some or all of the problems in this video might be more advanced that what your class is doing, so if you start getting scared, hit stop!

01-FOIL of 2 by 2

admin — Fri, 24 Aug 2012 00:58:43 +0000

Basic FOIL on 2-by-2 parentheses In this video we'll learn the most common FOIL situation, multiplying parentheses that each have two terms in them (a.k.a. binomials). Most students don't have too much trouble with the concept of FOIL; the most common mistake is forgetting one of the terms. First, Outside, Inside, Last is one way not to forget any terms, but I'll also show you my favorite graphical technique: drawing rainbows over and under to keep track.

FOIL — chapter listing

admin — Fri, 24 Aug 2012 00:50:07 +0000

FOIL (a.k.a. "Multiplying Out Parentheses") Basic FOIL on 2-by-2 parentheses FOIL On Bigger Problems (trinomials)	FOIL is an acronym that helps you multiply out parentheses in problems like (x-5)(x+2), and you've got to be able to do this before you can factor. This chapter covers the easier 2-by-2 FOIL problems, as well as 2-by-3 and beyond.

Variation – Joint & Inverse

admin — Fri, 24 Aug 2012 00:42:15 +0000

Variation - Direct, Inverse & Joint Direct & Inverse Variation: Two Variables Joint Variation: Three or More Variables	When a word problem talks about two things being "proportional", this is what they're talking about. Or maybe they're "inversely proportional". "Joint" variation just refers to when you have three things that are proportional or inversely proportional instead of just the two, which is basically just ratios in disguise.

02-Joint Variation

admin — Fri, 24 Aug 2012 00:37:36 +0000

Joint Variation: Three or More Variables These problems are exactly like the problems in the previous video, except instead of 2 variables there are three or four. Either way, same series of steps! "Directly" will still mean multiply, and "inversely" will still mean divide, and "plug and chug" will still be in your future. CAUTION: this video won't make a ton of sense unless you watch the one before it, so I'd recommend that first.

01-Direct & Inverse Variation

admin — Fri, 24 Aug 2012 00:33:26 +0000

Direct & Inverse Variation: Two Variables These two types of problems always involve two letters (usually x and y) and usually start the same way: if the problem has the words "varies directly" in it (or says two things are "proportional"), you just write down "y=kx" and start plug-and-chugging. If the problem says "varies inversely" (or variables are "inversely proportional"), you write down y=k/x and start plug-and-chugging. Sound too easy? What can I say: the same four steps will get you through every one of these things.

01-Factoring Stuff Out

admin — Fri, 24 Aug 2012 00:20:10 +0000

Factoring Stuff Out (a.k.a. "distribution in reverse") Instead of taking a problem like 2(x-3) and distributing it to 2x-6, we're going to do the exact opposite: start with 2x-6 and break it up into 2(x-3) by pulling out common factors. Seem like a waste? It's a necessary skill that you'll see throughout your math career, and it's a great lead-in for the more difficult type of factoring with two sets of parentheses, coming up in the next videos.

04-Hard Multi-Step Percent Problems

admin — Thu, 23 Aug 2012 04:23:33 +0000

Hard Multi-Step Percent Problems (SAT) When percent problems get hard, especially on standardized tests like the SAT, it's often because it's a two-step process. For example, a retail item is marked down once, then marked down again. Or, perhaps something gets bought and sold a couple times. Regardless of the exact question they're asking, the burn is always the same, and this video will show you how to always use the right denominator!
