Answer:
I can help you just tell me what you need help with?
1. b=-4
(x+1)(x-4)
2. b=2
(x-1)(x-2)
3. b=-18
(x+3)(x-6)
4. b=-10
(x+2)(x-5)
Answer: Solved.
Step-by-step explanation: The calculations are as follows -
(12) Given zeroes are 5, -3 and -1 + 3i. So, the other conjugate of -1 + 3i, i.e., -1 - 3i will also be a root of the polynomial. So the polynomial f(x) will be of degree 4 and is given by
(13) Given polynomial is
Now, we will substitute the rational numbers in place of 'x' and check whether the value of f(x) becomes zero or not.
We will see that
Also, the polynomial is not zero for any rational number.
(14) Given,
So,
Thus, the problems are solved.
