Question

find a if (x-a) us a factor of x^6-ax^5 +x^4 -ax^3 +3x-a+2​

Answer 1

Answer:

a= -2

Step-by-step explanation:

if x-a=0 is a factor of equation than it satisfies the equation

x=a

put the value of a in given equation

(a) ^6-a*(a) ^5+(a) ^4-a*(a) ^3+3*a-a+2=0

a^6-a^6+a^4-a^4+3a-a+2=0

2a+2=0

a=-2
