 | Here’s the video for today –remember,the test on chapter 11 is next Wednesday! Life it is not just a series of calculations and a sum total of statistics,it’s about experience,it’s about participation,it is something more complex and more interesting than what is obvious. Daniel Libeskind Here’s the video for the content today. Please watch closely as I will not cover this another day and youwill be expected to know the material when I return. I have alos loaded the notes from this video on my blog. Thanks! Here’s the notes for the content today. Please look over them closely as I will not cover this another day and you will be expected to know the material when I return. I have also loaded the video for these notes on my blog. Thanks! Addition and subtraction are the hardest things you’ll be doing with rational expressions because,just like with regular fractions,you’ll have to convert to common denominators. Everything you hated about adding fractions,you’re going to hate worse with rational expressions. But stick with me;you can get through this! Let’s refresh by looking at an . . . →Read More:Algebra II:Adding/Subtracting Rational Expressions… For dividing rational expressions,you will use the same method as you used for dividing numerical fractions:when dividing by a fraction,you flip-n-multiply. For instance: Perform the indicated operation: To simplify this division,I’ll convert it to multiplication by flipping what I’m dividing by;that is,I’ll switch from dividing by a fraction to . . . →Read More:Algebra II:Dividing Rational Expressions With regular fractions,multiplying and dividing is fairly simple,and is much easier than adding and subtracting. The situation is much the same with rational expressions (that is,with polynomial fractions). The only major problem I have seen students having with multiplying and dividing rationals is with illegitimate cancelling,where they try to cancel terms . . . →Read More:Algebra II:Multiplying Rational Expressions Taking the absolute value of a negative number makes it positive. For this reason,graphs of absolute value functions tend not to look quite like the graphs of linear functions that you’ve already studied. Because of how absolute values behave,it is important to include negative inputs in your T-chart when graphing absolute-value functions. If . . . →Read More:Algebra II 2.7-Graphing Absolute Value Functions Today we’ll be looking at Graphing Quadratic Inequalities –I’ll post some more material towards the end of the day,but for right now,here;s the video presentation –Have a great Thanksgiving! | |||
