Ayouth group is setting up camp. rain is predicted, so the campers decide to build a fly, or rain cover, over their tent. the fly will be 12 feet high and 16 feet wide. the scouts are building the frame for the fly with two poles slanted and joined together at the top of the tent.
the minimum length of the slanted poles needed to support the fly .

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.
