The five numbers 1, 2, 3, 4, 5 are written respectively on the five disks of the same size and placed in a hat. two disks are drawn without replacement from the hat and the number written on them are observed. list the 10 possible outcomes of this experiment as unordered pairs of numbers. write the outcome in the format such as (1,2) and separate different outcomes by comma or space.

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.
