Question

if P(x)=x square -5x+1 then evaluate P(2)-P(-1)+P(1/3)​

Answer 1

Step-by-step explanation:

on squaring (1-5x) we get 25x²-10x+1 --->©

now puting,

P(2) in ©, we get 100-20+1=81

P(-1) in ©, we get 25+10+1=36

P(1/3) in©, we get (25/9)+(10/3)+1=64/9

Now,

P(2)-P(-1)+P(1/3) on substituting there value we get,

81-36+(64/9)

45+(64/9)

(405+64)/9

469/9

52.11 is the answer
