Would you mind typing it out for me? I don't quite understand exactly what you are asking. For example, x to the second power minus 4x over x to the second power minus 16 would be... x^2-4x/x^2-16 Do you mind typing it out like that? Because what you wrote makes no sense at all.
3x^2 - 27 = = 3(x^2 - 9) = 3(x^2 - 3^2) = 3(x - 3)(x + 3)

x^2 +8x -9 is equivalent to (x+9)(x-1) when factored
x 2 - 5x - 36 = 0; factor. (x-9)(x+4) = 0; set each factor = 0. x - 9 = 0 and x + 4 = 0 So, x = 9 and x = -4.

x(x - 1)

(x - 9)(x + 9)
It is a polynomial expression in x. What about it?
simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34
(x - 5)(x + 5)
'x' is +4 or -4 .
(x + 1)(x - 1)
x^2(x - 4)(x + 4)
3x^2 - 27 = = 3(x^2 - 9) = 3(x^2 - 3^2) = 3(x - 3)(x + 3)
(x - 3)(x + 3)(x2 + 9)
