Question

Examine whether x-1 is a factor of the polynomial 2x3-5x2+x+2. ​

Answer 1

Step-by-step explanation:

x-1=0

x=1

substitute x=1 in 2x^3-5x^2+x+2

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

=2-5+1+2

=5-5

=0

so x-1 is factor of given equation

Answer 2

Answer:

x+1 =1

Step-by-step explanation:

x=1 substitute x=1 in 2x×3-5x×2+x+2. =2-5+1+2. =5-5. =0
