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
A quadratic equation, if there's an equals stil to come... Otherwise it's just an expression.
It is a polynomial expression in x. What about it?
Infinity.
8.2 x 102 ÷ 6.3 x 104 ≈ 1.302 x 10-2
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.
x2-x-56 = (x+7)(x-8) when factored
'x' is +4 or -4 .
7(x - 2)(x + 2)
(-2)^4 = -2 x -2 x-2 x-2 = +16 ( a minus times a minus is plus)
which of the following is a factor of x2 - 5x - 6
-24 = -2 x -2 x -2 x -2 = 16
That factors to 5(x - 4)(x + 4)(x2 + 16)
This factors as (x5 - 4) (x5 + 4).
First, factorising, we get: x2 - 6x - 16 = (x - 8)(x + 2). Then, (x2 - 6x - 16) / (x - 8) = x + 2.
x = plus or minus two thirds
(x - 16)(x + 2) x = 16 or -2
