Question 553000: Use the difference-of-squares pattern to factor.
x^6 - 9y^2 =
Comment: I'm having trouble figuring out how to factor the x^6 , none of the examples in the chapter have none square x values. also, none of the rules describe how to do it with x^6.
Thank you, Anthony

Question 553525: Solve this equation by using the square root property: 4x^2-28x+49=5
I do school online so all I have as a resource is the text book and the only examples they gave where only problems like this:
x^2+10x+25=49
(x+5)^2=49
x+5=±√49
x+5=±7
x=-5±7
x=-5+7 or x=-5-7
x=2 or x=-12
{2,-12}
I understand how they did that problem but they showed no examples on what to do if x^2 had a number in front of it like 4x^2.

Question 558608: Hi could someone please help me, I have an Expression that needs rationalizing by taking the conjugate:
3√10/6-8√3
it says the answer is -3√10-4√30/26 But I got nothing like this, here is what I tried:
I multiplied the top and bottom by the conjugate of the denominator 6-8√3, which I thought was 6+8√3.
So I did this:
3√10/ *6+8√3 = 18√10+8√3*3√10/
6-8√3 *6+8√3 36-64*3
Obviously this is not even close to the correct answer, could someone please explain to me all the steps I need to do and where I am going wrong.
Many Thanks Jim.
