Here is another alternative approach. Let's factorise x³ - 27x + 54. x³ - 27x + 54 = x³ + (ax² - ax²) + (bx - bx) - 27x + 54 - (1) = (x³ - ax² + bx) + (ax² - (b + 27)x + 54) = x(x² - ax + b) + a(x² - (b + 27)x/a + 54/a) So, we'd like a² = (b + 27) and ab = 54 so that x² - ax + b = x² - (b + 27)x/a + 54/a and hence we can factorise the entire expression. So, we want b + 27 to be a square, and a to be a factor of 54. The first square larger than 27 is 36, so try b + 27 = 36, so b = 9 and a = 6. Looking good so far. So placing a = 6 and b = 9 in (1) then x³ - 27x + 54 = x³ + (6x² - 6x²) + (9x - 9x) - 27x + 54 = (x³ - 6x² + 9x) + (6x² - 36x + 54) = x(x² + 6x + 9) + 6(x² - 6x + 9) = (x + 6)(x² - 6x + 9) = (x + 6)(x - 3)² So the solutions are x = -6, 3 (double root).

Strictly it is an excellent approach to solve this type of quadratic equation. By putting x=3y this equation can be solved? I have divided it by x-1, x+1, x-2 and x+2 but there was a reminder. Can x+3 divide it?

Thank you sir for clear my concept

It is rather a shrewd and ingenious way to fathom out roots of cubic equations. It could be solved by hit and trial, by contemplating one root and determining a factor which would then divide the equation to form a quadratic equation in form of quotient. I'm in class 10 and this seems very acquainted go me. Out of curiosity, who's the audience for the video?

An alternative approach is to used Descartes Rule of Sign and the Rational Root theorem. Descartes Rule of Signs says there are 0 to 2 +ve real roots and 1-ve real root. Possible rational roots by the Rational Root theorem are x = ±1, ±2, ±3, ±6, ±9, ±18, ±27 and ±54. I'd start checking the -ve roots, as at least we know one exist. When we try x = -6 the equation is satisfied and we can stop checking the negative roots. Then we just use synthetic division to find the quadratic factor, and then the quadratic formula to solve the quadratic equation.
