54.3 squared
81 x 2 - 16 = 146
Negative sixty-four minus four squared is equal to -80.
(2x - 1)(2x + 3)
1 over x2 - 4 is the multiplicative inverse of x2 minus four 1/x2 - 4
-22 - -22
By factoring I get x-3 divided by x+3
There are no rational factors.
(x + 2)(x - 2)
54.3 squared
x^2 - y^2 - 4 is in its simplest form.
x = ? 42 = x squared minus x
81 x 2 - 16 = 146
Negative sixty-four minus four squared is equal to -80.
(2x - 1)(2x + 3)
1 over x2 - 4 is the multiplicative inverse of x2 minus four 1/x2 - 4
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.
