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).

What is the square root of x to the power of 2 minus 14x plus 49?
(x - 7) is.
Evaluate - -7 to the second power?
7 x 7 = 49
What is 5x to the third power plus x to the second power minus 4 to the third power minus x tot the sixth power plus 19x to the third power?
simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34
What is 49 minus X squared over X minus 7?
49 - x2 = -(x2 -49) = - (x-7)(x+7) divide by x -7 Answer: -(x+7) = -x-7
What is x to the 4th power minus 49?
x4-49 is the difference of two squares when factored as (x2-7)(x2+7)
X to the second power minus 9?
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.
X to the 2nd power minus 4x over x to the second power minus 16 divided by x to the 2nd power plus 2x minus 24 over x to the 2nd power minus 2x minus 24?
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.
What is the square root of x to the power of 2 minus 14x plus 49?
(x - 7) is.
How do you factor x to the second power minus x?
x(x - 1)
If x plus y 13 and x-y2 What is the value of x to the second power minus y to the second power?
15
Evaluate - -7 to the second power?
7 x 7 = 49
Negative 5x to the second power plus 6 plus x to the second power minus 1 plus five x to the second power?
It is a polynomial expression in x. What about it?
What is 5x to the third power plus x to the second power minus 4 to the third power minus x tot the sixth power plus 19x to the third power?
simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34
What is 49 minus X squared over X minus 7?
49 - x2 = -(x2 -49) = - (x-7)(x+7) divide by x -7 Answer: -(x+7) = -x-7
What is x to the 4th power minus 49?
x4-49 is the difference of two squares when factored as (x2-7)(x2+7)
How do you factor X to the second power minus twenty-five?
(x - 5)(x + 5)
When X to the second power minus 16 equals 0?
'x' is +4 or -4 .
