Expand & Simplify -3/4(3x+2)-2

To solve this exercise properly, you'll have to write it
according to mathematic rules.


For instance, because of the
lack of brackets, we do not know if the first factor is the fraction (-3/4) or just
(4).


If it is (4), we'll solve it in this
way:


-3/(12x + 8) - 2 (we have opened the brackets from
denominator)


We'll multiply -2 by the denominator
(12x+8)


(-3 - 2*(12x +
8))/(12x+8)


(-3 - 24x - 16)/(12x +
8)


We'll combine like
terms:


(-19-24x)/(12x +
8)


The  result of the expression above,
written in this manner -3/4(3x+2)-2, is (-19-24x)/(12x +
8).

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 ...
