Some students are taking a math contest in which each student takes one of four tests. One third of the students take the first test, one fourth take the second test, one fifth take the third test, and 26 students take the fourth test. How many students
are taking the contest in total?

PLS GIVE EXPLANATION!!

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
