Given Equation is 2x^3 + 54.
2(x^3 + 27)
2(x^3 + 3^3)
We know that (a^3 + b^3) = (a + b)(a^2 - ab + b^2)
2(x + 3)(x^2 - 3x + 3^2)
2(x + 3)(x^2 - 3x + 9).
Hope this helps!

2x^3+54=2(x+3)(x²-3x+9)
Explanation :
First take out the common factor of 2
2(x³+27)
Then recognize this as the sum of the cubes. To factor cubes, mesmerize the expression
a³+b³=(a+b) (a²-ab+b²)
Then 2x^3+54=2(x+3)(x²-3x+9)
