Answer:
x =3
Step-by-step explanation:( x − 3 ) ( x + 2 ) ( x 2 + x + 1 ) = 0
Set x − 3
equal to
0
and solve for x .
x = 3
Set x + 2
equal to
0
and solve for x .
x = − 2
Set x 2 + x + 1
equal to
0
and solve for x .
x= − 1 − i √ 3 2 , − 1 + i √ 3 2
The solution is the result of x − 3 = 0 , x + 2 = 0 , and x 2 + x + 1 = 0 . x = 3 , − 2 , − 1 − i √ 3 2 , − 1 + i√ 3 2
