Solution:
Here, f(x) = 3x2 + x - 28 and g(x) = 6 -x
Now, f(x).g(x)
= (3x2 + x - 28) (6-x)
= 18x2 + 6x - 168 -3x3-x2 + 28x
= -3x3 + 17x2+ 34x - 168 is the required answer

If f(x) = 3x2 + x - 28 and g(x) = 6 -x are the two polynomials. Find the value of f(x).g(x)
Solution:
Here, f(x) = 3x2 + x - 28 and g(x) = 6 -x
Now, f(x).g(x)
= (3x2 + x - 28) (6-x)
= 18x2 + 6x - 168 -3x3-x2 + 28x
= -3x3 + 17x2+ 34x - 168 is the required answer
