Assuming the question is written as: x2+11x-12 This would factor to: (x+12)(x-1)
66x^3 - 36x^2 = 6x^2(11x - 6) 55x - 30 = 5(11x - 6) 66x^3 - 36x^2 + 55x - 30 = (6x^2 + 5)(11x - 6)
(x - 6)(x2 + 6x + 36)
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: (-11 plus or minus the square root of -31) divided by 4.x = -2.75 + 1.3919410907075054ix = -2.75 - 1.3919410907075054iwhere i is the square root of negative one.
Setting to zero may help. 36 - X2 = 0 36 = X2 take square root each side (+/-) 6 = X ========
x2 -11x-12= (x-12)(x+1)

The factors of (x2 + 11x + 30) are (X + 5) and (x + 6)You want to look for two numbers, when multiplied equal 30, and when added equal 11. Start with factors of 30, and see what they add to: 5+6=11, and 5*6=30.
It doesn't factor evenly if it were x**2-11x+10: x**2-11x+10 = (x-1)(x-10)
Not possible to be specific since you have not provided the sign of the term in x, but there are two possible factorisations; (x + 3)(x + 8) = x2 + 11x + 24 and (x - 3)(x - 8) = x2 - 11x + 24
x^2 + 11x + 6 has no rational zeros.
x2 - 11x + 24 = (x - 3)(x - 8)
x2 + 11x + 30 = 0 (x + 5)(x + 6) = 0 so the roots are -5 and -6
To solve for x: x2 = 11x - 10 x2 - 11x = -10 x2 - 11x + 10 =0 (x - 1)(x - 10) = 0 x = {1, 10)
