(x - 5)(x + 5)
(x + 1)(x - 1)
(2x - 3)(3x + 2)
x^2(x - 4)(x + 4)
(x - 2)(x + 2)
a3x2 - 216x2 factors to x2(a - 6)(a2 + 6a + 36)
Just X to the second power minus nine. You can't subtract nine from x to the second power unless you know what x is.
(2x - 1)(x + 4)
x cubed minus 216
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.
which of the following is a factor of x2 - 5x - 6
x(x + 1)(x - 1)
