ANSWER
The correct answer is option B
EXPLANATION
The equations are
and
When we multiply the second equation by , we obtain;
When we combine this new equation with equation (1).
We can see that has been eliminated from the equation.
We can then, solve for and then substitute the result in to any of the equations to find
.
Hence the correct answer is option B
Answer:
1) Option c) is correct ie., 5 real and o non-real
2) Option b) is correct ie., (4, ,
, 2,2)
Step-by-step explanation:
Given polynomial function is
To find zeros equate f(x) to zero ie.,
By synthetic division
| 1 0 -3 0 -2
-1 | 0 -1 1 2 2
|_________________
1 -1 -2 2 0
Therefore x=-1 is a zero
| 1 -1 -2 2
1 | 0 1 0 2
|___________________
1 0 -2 0
x=1 is the zero
and
Option c) is correct ie., 5 real and o non-real
2) Given polynomial function is
To find zeros equate f(x) to zero ie.,
(or)
or
Therefore x=4, of multiplicity of 2 and x=2 multiplicity of 2
Option b) is correct ie., (4, ,
, 2,2)
