I haven't taken a math class since high school and I'm 23 now. I jumped right into Precalc 1 for the summer and the first chapter kicked my ass. I completely forgot how to factor and do LCD with algebraic equations and my professor just breezes by it like its nothing.(adsbygoogle = window.adsbygoogle || []).push({});

Can anyone explain the general principles of factoring trinomial equations? Example x^2 + 5x 6 = 0, factor that. (Or is the term called FOIL?)

LCD is a problem too, I know the concept is multiply both denominators together to get the LCD to cancel out... but what if the equation is complex like (2+5x)/(x^2+4x+3) + (3-4x)/(5x+8) = 7x^2 + 7

another one was x/8 + 2x/4 = 25

Any help and or practice problems would be greatly appreciated, i need to catch up!
