Special factorization Completely factor the following expressions 250x^3-128 X^6-1 X^6+1 x^2-8xy+16y^2-25 16x^4a-y^8a ((8x^3)/125)+(64/y^3) I was given a set on how to do this skill, but it didn't really cover on how to attack these kind of expressions. I...

Eliminate the complex fractions (5/8)/(-2/3) (x^-1+y^-1)/(x+y) (1/x+1/y)/(x+y) (xy/xy/) I was trying to find the lcd for the first one but couldn't figure it out. For the second one, I got to as far as getting the reciprocal of the numerator and then mult...

Find the inverses 1) y=9/x x=9/y xy=9 y=9/x Which is wrong I believe 2) y=(2x+1)/(3-2x) How do I get rid of the ys after I replace the xs with them?

Solving fractional equations 1) (1/x-3)+(1/x+3)=(10/x^2-9) 2) (5/2x)-(5/3(x+5)=(5/x) 3) (2x-1/x-1)-(3x/2x+1)=(x^2+11/2x^2-x-1) I just have a problem knowing what the lcd is. For the first one, i know I had to m,multiply the left side by x-3 and x+3, but i...

Trig ientities

Exponential functions and logarithms 1) ln(1/cuberoot e^2) 2)e^ln12 3)log3(root3)^5 4) 3^x-2=18 5)e^3x+=10 6)8^x=5^2x-1 I'm really not positive on how to solve these

Please can some one help

For the second example, how did you get to 2x/5 and 4/5?

So the first one, all I had to do was divide it normally? Do I do that if there are no lcd's for problems like that?

OHHHH, wait, correct me if i'm wrong, but the lcd for problems like this are most likely the denominator of the 2 fraction being combined?

Thank you so much

THANK YOUU

Trig identites (1/1+tanx)+(1/1+cotx)=1 For this one, I wanted to know if 1+tanx is the same as 1+tan^2x, because 1+tan^2x=sec^2x These are the ones that I have no idea how to do: ((cosx-cosy)/(sinx+siny))+((sinx-siny)/(cosx+cosy))=0 (sin^3x+cos^3x)/(sinx+...

I really need help
