━━━━━━━━━━━━━━━━━━━━━━

Given,

=> value of x = 2

=> equation $3x-3x{^2}-2x+k$

put x = 2 in the equation.

━━━━━━━━━━━━━━━━━━━━━━

$3(2) -3(2) {^2}-2(2) +k$

$6-12-4+k$

$6-16+k$

$-10+k$

Now, -10 + k will be equal to zero.

-10 + k = 0

k = 10

Value of k is 10.

GIVEN:

p(x)=3x-3x^2-2x+k =-3x^2+x+k

value of x=2.

TO FIND:

Value of k.

ALGORITHM:

FIRST EQUATE P(X) =0 THEN SUBSTITUTE THE VALUE X IN THE EQUATION.

SOLUTION:

=>p(x)= -3x^2+x+k =0

=>p(2)=-3×2^2+2+k=0

=>-12+2+k=0

=>-10+k=0

=>k=10 (Answer)
