Simplify:  $$3(9x^3 - 6x^2 + 30) - 9(3x^3 - 2x + 30)$$​​

Correct option is C

Given: 

$$3 ( 9x^3 - 6 x^2 + 30) -9 ( 3x^3 - 2x + 30)$$  

Solution : 

Solving the Expression : 

$$3 ( 9x^3 - 6 x^2 + 30) -9 ( 3x^3 - 2x + 30)$$

$$27x^3 - 18x^2 + 90 - 27x^3 + 18x - 270 = 0$$ 

$$- 18 x^2 + 18 x - 180 = 0$$ 

$$-18 (x^2 - x +10)$$ = 0
