Answer:
The zeros of given expression is -1, and
Step-by-step explanation:
Given expresssion is
To find zeros of given expression we have to equate the expression to zero.
ie.,
By using synthetic division
-1 | 1 3 6 4
| 0 -1 -2 -4
|________________
1 2 4 0
Therefore (x+1) is a zero
Now the quadratic equation is
For quadratic equation we have
Here a=1 ,b=2 and c=4 now substitute the values
where
Therefore and
Therefore the zeros are -1, and
