Find all the zeros in the equation x^4-6x^2-7x-6=0 show your work

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
