Answer 2

Answer:

-1 would be the answer.

Step-by-step explanation:

x(x-3) = -1

Take cube on both sides:

x³(x-3)³ = -1

So,

x³(x³-27-9x²+27x) = -1

=> Now, from given eqn x²-3x = -1 => x² = 3x-1

So, put the value of x² in cubic eqn.

=> x³(x³-27-9(3x-1)+27x) = -1

=> x³(x³-27-27x+9+27x) = -1

=> x³(x³-18) = -1
