Question

For the polynomial P(x) = x5(power 5 ) + 4x3(cube) - 5x2(square) + x - 1
One of the factor is - a. (x+1) b. (x-1) c. (x) d. (x+2)

Answer 1

Step-by-step explanation:

x^5+4x^3-5x^2+x-1

x^5-x^4+x^4-x^3+5x^3-5x^2+x-1

x^4(x-1)+x^3(x-1)+5x^2(x-1)+1(x-1)

(x-1) (x^4+x^3+5x^2+1)

so, (x-1) is the factor
