Step-by-step explanation:
x^2 - 3x + 2
= x^2 - 2x - x + 2
= x(x - 2) - 1(x - 2)
= (x-1)(x-2)
p(x) = 2x^4 - 5x^3 + 2x^2 - x + 2
When p(x) is divided by x-1, then remainder = p(1)
p(1) = 2(1)^4 - 5(1)^3 + 2(1)^2 - 1 + 2
= 2 - 5 + 2 - 1 + 2 = 0
When p(x) is divided by x-2, then remainder = p(2)
p(2) = 2(2)^4 - 5(2)^3 + 2(2)^2 - 2 + 2
= 32 - 40 + 8 - 2 + 2 = 0
Since polynomial p(x) is divisible by the factors of x^2 - 3x + 2, then x^2 - 3x + 2 will exactly dive polynomial p(x).
