Mar 02, 2009 which aqueous solution would have the lowest vapor pressure at 25 degrees celsius? 1 M Na3PO4 c. 1 M sucrose, C12H10O11 d. 1 M glucose, C6H12O6 in the responses, all 'M's are italicized. I know the answer is not C and i believe it is B. But i am more interested in knowing why the correct answer is correct. First correct answer will get a best answer. I truly want to.

Form a polynomial whosezeros and degrees are given.
Zeros:-3,-2,3; degree 3
----------
Each zero, eg, z, contributes a factor (x - z)
Multiply (x+3)*(x-3)*(x+2)
---------------
=
=
B
----
I don't know what the a= 1 means.

Sorry dear, I can't understand the problem completely but I am solving it to form a polynomial whose zeros are -3, -2 & +3 with degree 3
The simple method to find the polynomial is just write the factors of it and multiply them.
In order to find the factors, just subtract the zeros separately from a variable say 'X'
So the factors of the polynomial are
X - (-3) i.e. (X + 3)
X - (-2) i.e. (X + 2) &
X - (+3) i.e. (X - 3)
on multiplying these factors, we will get the required polynomial,
i.e. (X + 3)(X + 2)(X - 3)
i.e.
Now I don't know what is A, B, C & D
If these are the options for the correct answer then what is 'a = 1'
Please reply
