If the three solutions of the equation f(x) = 0 are -2, 0, and 3, what are the three solutions of the equation f(x - 2) = 0?

Given that 0, -2, and 3 are the zeros of the function
f(x).


Then x, (x+2), and (x-3) are the factors of
f(x).


Then f(x) =
x(x-3)(x+2).


Now we need to find the solutions for
f(x-2)


Then, we will substitute with (x-2) in place of x
into the equation.


==> f(x-2) = (x-2) ( x-2 -3)
(x-2+2)


==> f(x-2) =
(x-2)(x-5)(x)


Then the zeros of f(x-2) are 2, 5, and
0


Then the solution for f(x-2) are 0, 2, and
5.

Can (sec x - cosec x) / (tan x - cot x) be simplified further?

Given the expression ( sec x - csec x ) / (tan x - cot x) We need to simplify. We will use trigonometric identities ...
