A simple way to do this is to write something that will produce division by zero at those points. Something like 1 / (x-6)(x-3). You can put anything you like into the numerator, instead of the 1.
x/3
3 - k
3+c
Three and eight times a number.
x4 - 3
x/3
It is not possible to answer the question since no equation is given in the question: only an expression.
3 - k
Re-write it with a root. If the power of the expression is less than 1, for example x1/3, the expression could be rewritten as cube root of x.
A fraction is a division expression. 3/4 = three divided by four
3+c
Here is a non-conventional answer: -3 / 3 - 3 + 33 = 29 Use five 3's to write an expression whose value equals 29?
6•2+6•3
Three and eight times a number.
33 + (3 + 3)/3
x4 - 3
As an algebraic expression it is: k-3
