What is the greatest common factor of x9 and x2?
The GCF is x2.
What is the factor of X4 plus X2 - 42?
x4 + x2 - 42 Let x2 = t, so that x4 = t2 t2 + t - 42 since -42 = 7(-6) and 7 + (-6) = 1, then t2 + t - 42 = (t - 6)(t + 7) = (x2 - 6)(x2 + 7) By replacing t with x2. So we have, x4 + x2 - 42 = (x2 - 6)(x2 + 7) = [x2 - (square root of 6)2](x2 + 7) = (x - sq. root of 6 )(x + sq. root of 6)(x2 + 7)
What is the LCM of x2 plus 16x plus 64 and x2 plus 3x-40?

How do you factor 2x2-8y2?
First it would be easiest to factor out the 2. 2x2-8y2 2(x2-4y2) Then you factor the part in the parenthesis as follows 2(x-2y)(x-2y) which can be simplified as 2(x-2y)2

Can the square root of -x2 plus 16 be simplified?
It can be factored. Whether the factored form is simpler or not is a matter of opinion.sqrt( 16 - x2 ) = sqrt [ (4 + x) (4 - x) ]
What is x6 x2 simplified?
Guessing they are powers and no operational symbol is between the two (ie a multiplication is assumed), then: x6 x2 = x6 + 2 = x8 Otherwise, re-ask with words for missing symbols, eg "what is x to the power 6 plus x to the power 2 simplified"
What does x squared minus 2x equal?
x2 - 2x = x(x-2) and that cannot be simplified further.
