Question

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

Answer 1

Answer:

Step-by-step explanation:

2x³-5x²+x+2

let x-2=0 is a factor then, x=2

= 2(2)³-5(2)²+(2)+2

= 16-20+4

= 20-20=0

then (x-2) is a factor thiss polynoimial

Answer 2

ANSWER:

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

x-1=0

x=1

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

=2-5+1+2

=5-5

=0

☆Therefore, x-1 is a factor of the polynomial 2x^3-5x^2-x+2.
