What is the answer to x squared minus 16 divided by x minus 4 plus x squared equals 16?
Your equation is not clear I can understand it in two ways (x2-16)/x-4+x2=16 x=-4.59486 x=-0.793499 x=4.38835 or x2-(16/x)-4+x2=16 x=3.50466 x=-0.864641 x=-2.64002
What is x to the 2nd power minus 9x plus 90?
A quadratic equation, if there's an equals stil to come... Otherwise it's just an expression.
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 the limit as x approaches infinity of x plus x to the 3rd power plus x to the 5th power all divided by 1 - x to the 2nd power plus x to the 4th power?
Infinity.
How do you factor x squared minus 2x minus 8?
(x + 2)(x - 4)
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 x to the 2nd power minus x minus 56?
x2-x-56 = (x+7)(x-8) when factored
When X to the second power minus 16 equals 0?
'x' is +4 or -4 .
Factor 7x to the 2nd power minus 28?
7(x - 2)(x + 2)
What is-2 to the 4th power?
(-2)^4 = -2 x -2 x-2 x-2 = +16 ( a minus times a minus is plus)
Which is a factor of x to the 2nd power minus 5x minus 6?
which of the following is a factor of x2 - 5x - 6
What is minus 2 to the 4th power?
-24 = -2 x -2 x -2 x -2 = 16
What is 5x to the 4th power minus 1280?
That factors to 5(x - 4)(x + 4)(x2 + 16)
How do you factor x to the tenth power minus 16?
This factors as (x5 - 4) (x5 + 4).
X squared minus 6x minus 16 divided by x minus 8?
First, factorising, we get: x2 - 6x - 16 = (x - 8)(x + 2). Then, (x2 - 6x - 16) / (x - 8) = x + 2.
What are two real solutions of x to the 4th power 16 over 81?
x = plus or minus two thirds
What is x to the 3rd power minus 3x to the 2nd power minus 28x?
x3 - 3x2 - 28x = x (x2 - 3x - 28) = x (x - 7) (x + 4)The numerical value of all this, of course, depends on the value of 'x',and it can change in a flash whenever the value of 'x' changes.
