Solve the equation. if there is no solution, write no solution. –2 |h – 7| = –28 a. h = –7, h = 21 b. h = 21, h = –21 c. no solution d. h = 7, h = –21

The answer would be option A. h = –7, h = 21

Step-by-step explanation:

Question: -2 |h-7|=-28

Substitution: -2 |-14 (-7-7)| = -28

-2*14=-28

Substitution 2:

-2 |14 (21-7)|=-28

-2*14=-28

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.
