Using the combination formula, and considering that the list has 6 ingredients, it is found that 20 groups of 3 different ingredients can go on a taco.
The order in which the ingredients are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.
<h3>Combination formula:
</h3>
is the number of different combinations of x objects from a set of n elements, given by:
In this problem, 3 ingredients are chosen from a set of 6, hence:

20 groups of 3 different ingredients can go on a taco.

Next time, please list the possible answer choices. Without them, all I can do is to attempt this problem without having those choices as guidelines.
I must assume that your expression x^4-5x+3/x^2+7 actually meant:
5x + 3
x^4 - ---------------
x^2 + 7
and I assume that this result was one of the several possible answer choices.
