Complement of an angle = 90° - x.
Supplement of the complement of an angle = 180 - (90 - x).
= 180 - 90 + x
= 90 + x
Supplement of the complement of an angle less the complement of an angle = (90 + x) - (90 - x)
= 90 + x - 90 + x
= 2x
Now, the quotient of the supplement of the angle and the number 3 is 
.
It is given that supplement of the complement of an angle less the complement of an angle exceeds the quotient of the supplement of the angle and the number 3 by 73.
Therefore, 2x = 
Multiply both sides by 3.
6x = 180 - x + 219
= 399 - x
Add x to both sides.
6x + x = 399
7x = 399
Divide both sides by 7.
x = 57
Hence, the required angle = 57°.
X^4 - 3x^2 + 2 = 0
(x^2 - 2)(x^2 - 1) = 0
so either x^2 - 2 = 0 or x^2 - 1 = 0
so x^2 = 2 or x^2 = 1
so x = sqrt 2 , - sqrt2, 1 , -1 Answer

6 times what equals 84?
6 times what equals 84? In other words, what do you multiply by 6 to get 84? If "x" is "what" in the sentence, "6 times what equals 84?", then the equation to solve the problem is as follows:
6 • x = 84
Which can be written as:
6x = 84
To solve the equation above, we need to remove the 6 on the left side to make the x alone. To do that, we divide both sides by 6.
6x/6 = 84/6
6x/6 is x and 84/6 is 14 which means our equation will look like this:
x = 14
Thus, the answer to "6 times what equals 84?" is 14.
