The volume of the cube is 8 ft^3. what the length of each side?

The Solution is:

Use the cube volume formula, V = s³, where s is the side length.

Plug in 8 as V, and solve for s:

V = s³

8 = s³

Take the cubed root of each side:

2 = s

So, the length of each side is 2 feet.

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.

c
