Question

if x-1 is a factor of 3x³-9x²+x+y then value of k is​

Answer 1

Answer:

3(1)*3-9(1)*2+1+y

3 - 9 +1 +y

3-9+1= -y

-6+1=-y

-5 =-y

y=5

Answer 2

Answer:

in this question no variable k

this question is find y

Step-by-step explanation:

put x=1 in equation

3(1)³-9(1)²+1+y

3 - 9 + 1 +y

3-10+y

3-10 = - y

-7 = -y

minus minus will be cancelled so

7=y
