Question

if x-2 is a factor of this polynomial x4-2x3+ax-1 find the value of a is
​

Answer 1

Answer:

a=-1/2 may be the value of a...

Answer 2

Answer:

Hey there

As x-2 is a factor of polynomial

So

x-2=0

x=2 is a root of that Polynomial

Thus

Substituting Value of x

(2)^4-2(2)^3+a(2)-1 =0

16-16 +2a-1=0

2a=1

a=1/2

which is the required ans
