x = -1 or 15

Step-by-step explanation:

If the absolute value equals 8, the value of x - 7 can either be -8 or 8.

We first solve for when it is equal to -8:

x - 7 = -8

We can add 7 to both sides:

x = -1

Now we can solve for when it's equal to 8:

x - 7 = 8

We can add 7 to both sides:

x = 15

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.
