x squared plus 5
-22 - -22
By factoring I get x-3 divided by x+3
There are no rational factors.
(x + 2)(x - 2)
X squared is not an inverse function; it is a quadratic function.
x = ? 42 = x squared minus x
x^2 - y^2 - 4 is in its simplest form.
81 x 2 - 16 = 146
The "value" of the function at x = 2 is (x+2)/(x-2) so the answer is plus or minus infinity depending on whether x approaches 2 from >2 or <2, respectively.
(2x - 1)(2x + 3)
XX or X*X, can be written as X squared. The inverse of a function "sort of cancels it out". I know the inverse of a square is the square root. Since we need the inverse of X squared, it's inverse is the square root of X. sqrt(x)
xsquared minus x minus 72
Sin squared, cos squared...you removed the x in the equation.
x squared minus 12 x plus 36 = (x - 6)(x - 6)
(x - 5)(x + 4)
x + 1
Without that other number, all you've got is zero.
