Question

If ( x - 2) is a factor of x^3 - 2ax ^2+ax -1 pls

Answer 1

Answer:

Step-by-step explanation:

x-2=0

x=2

then we put x=2 in the given polynomial

p(x)=(2)^3-2a(2)^2+a(2)-1=0

p(x)=8-8a+2a-1=0

p(x)=2a-8a+7=0

p(x)=-6a+7=0

p(x)=-6a=-7

now, cancel the minus sign

and transfer the six on other hand

p(x)=a=7/6
