Question

verify whether x-1 is a factor of the polynomial 2x^3 - 5x^2 + x + 2

Answer 1

Step-by-step explanation:

x-1=0

x=1

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

=2-5+1+2

=0

Answer 2

Answer:

yes, 2x^ {3} - 5x^{2} + x + 2 x-1 is a factor of the following eq

Step-by-step explanation:

if x-1 would be factor it must be equal to zero

x - 1 = 0 ===> x = 1

p(x)= $2x^ {3} - 5x^{2} + x + 2$

p(1) = $2(1)^ {3} - 5(1)^{2} + 1 + 2$

     = 2 - 5 + 1 +2

     = 5-5

     = 0

so yes, 2x^ {3} - 5x^{2} + x + 2 x-1 is a factor of the following eq
