Question

2x^3 -5x^2+x+2 is the polynomials of the x-1

Answer 1

Answer:

Step-by-step explanation:- 2x^3-5x^2+x+2x-1 is divided by x-1

Step 1:-

Put divisor =o

X-1=0

X=1

Step 2:-

P(x)=2x^3-5x^2+x+2x-1

Putting x=1

P(1)=2(1)^3-5(1)^2+(1)+2(1)-1

=2(1)-5(1)+(1)+2(1)-1

=2-5+1+2-1

=-1

Here the remainder is not zero

So,

X-1 is not a factor of 2x^3-5x^2+x+2x-1
