Answer:

Step-by-step explanation:

p(x)=0

p(1)=a*1^2-3(a-1)*1-1

a-3(a-1)-1=0

a-3a+3-1=0

-2a+2=0

-2a=-2

a=-2/-2

therefore a=1

hope it helped:)

Answered by soni190403

Step-by-step explanation:

1 is zero of the polynomial (given)

p(x)=ax²-3(a-1)x-1

p(1)=a(1)²-3(a-1)(1)-1

0=1a-3(a-1)-1

0=a-3a+3-1

0=-2a+2

-2=-2a

-2/-2=a

1=a
