Answer:
Enter the polynomial and the value of x for which you want to find the value of the polynomial. The value of polynomial P(x) at x=a is P(a) .
Verified answer
Step-by-step explanation:
2x²-x-1
Using factorisation
2x²-(2-1)x-1
2x²-2x+x-1
2x(x-1)+1(x-1)
(x-1)(2x+1)
=> x = 1 and x = -1/2
Since these are the roots, value of polynomial will be 0 at x = 1 and x = -1/2
