Question

if p(x)=x^2 -5root2x -5root2 then find the remainder if p (x) is divided by x+5root2

Answer 1

Answer:

it's tooo easy you can do it.

Answer 2

Using Remainder theorem we say that when P(x) is divided by x+5√2 then remainder will be P(-5√2)    [Put x+5√2=0]

P(-5√2) = (-5√2)² - (5√2)*(-5√2) - 5√2 = 100-5√2

Hence, remainder is 100-5√2.
