Answer:
f(x) = x⁴-6x³-13x²+66x+72
Step-by-step explanation:
Factors are: (x+3)(x+1)(x-4)(x-6)
[(x+3)(x+1)][(x-4)(x-6)]
[x²+3x+x+3][x²-4x-6x+24]
(x²+4x+3)(x²-10x+24)
x⁴+4x³+3x²-10x³-40x²-30x+24x²+96x+72
f(x) = x⁴-6x³-13x²+66x+72
Answer:
Option D is correct.
D- A number that cannot be expressed as a fraction, , where p and q are integers
Step-by-step explanation:
Irrational number:
An irrational number can not be expressed as a fraction or ratio of integers, like
where p and q are integers
And also it can not be expressed as terminating decimal or repeating decimal
Example of the irrational number is given below.



Therefore option D (A number that cannot be expressed as a fraction, , where p and q are integers) is correct .
The greatest common factor is six.
Solve for x. The multiplicity of a root is the number of times the root appears.
x= -6.847415 (multiplicity of 1)
x= 0.793705 (multiplicity of 1)
