Question

1 - 100x^2
factor

Answer 1

1 - 100x^2

1^2 - (10x)^2

(1-10x)(1+10x) ... Use the difference of squares factoring formula here

So 1 - 100x^2 completely factors to (1-10x)(1+10x)

Answer 2

what about this one 9x^4y^2 - z^6
i got the answer as
(3x^2y+z^2)(3x^2y-z^3)
is that correct

Answer 3

9x^4y^2 - z^6

(3x^2y)^2 - z^6

(3x^2y)^2 - (z^3)^2

(3x^2y - z^3)(3x^2y + z^3)


So the expression factors to (3x^2y - z^3)(3x^2y + z^3)

Answer 4

I think you have the right answer. It's just that you probably made a typo when you wrote it out.
