Question

check whether polynomial 8x cube + 4x square- x + 1 is a multiple of 2x-1​

Answer 1

Answer:

No it is not a multiple.

Step-by-step explanation:

g(x):2x+1 == 2x+1=0 == x= -1/2

f(x):4x+4x²-x-1

Therefore on substituting the value of x in the equation we get,

4(-1/2)+4(-1/2)²-(-1/2)-1 = -2+1+1/2-1

                                  = -3/2

Since the value does not come as zero we can conclude that it is not the multiple of the given polynomial.
