Best Answer

This is considered an expression "x^2 - 49", or alternatively a function of the variable x. In that sense, when you apply the expression to a certain input (such as x=3) you obtain a number (3^2-49 = -40).

(x - 7) is.

7 x 7 = 49

simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34

49 - x2 = -(x2 -49) = - (x-7)(x+7) divide by x -7 Answer: -(x+7) = -x-7

x4-49 is the difference of two squares when factored as (x2-7)(x2+7)

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.

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.
