According to question
P(x) = 3 x^3 - 5 x^2 - 11x - 3
thus taking the equation to Zero
3 x^3 - 5 x^2 - 11x -3 = 0
Differentiating the equation with respect to x
9x^2 - 10x - 11 = 0
9x(x-10) = 11
thus
x= 21, 11/9
P(x) = 3 x^3 - 5 x^2 - 11x - 3
thus taking the equation to Zero
3 x^3 - 5 x^2 - 11x -3 = 0
Differentiating the equation with respect to x
9x^2 - 10x - 11 = 0
9x(x-10) = 11
thus
x= 21, 11/9
