Question

show that (X-1) (x-2) is a factor of the polynomial x^3 - x^2- 4x + 4 also find the zeros of the polynomial​

Answer 1

Step-by-step explanation:

x-1=0

x=1

P (1)=1^3-1^2-4×1+4

P (1)=1-1-4+4

P (1)=0

Hence x-1 is a factor of P (x).

x-2=0

x=2

P (2)=2^3-2^2-4×2+4

P (2)=8-4-8+4

P (2)=0

Hence x-2 is a factor of P (x).
