x^3 - 121x
The LCM is the absolute value of x.
xsquared minus x minus 72
3x2 - 11x - 4 = (x-4)(3 x + 1)
xcubed-1 Answer::(X-1)(Xsquared+X+1) when you factor xcubed minus a number its the same thing as x cubed minus y cubed and x cubed minus y cubed factors to:: (x-y)(xsquared+xy+y squared) the first factor, (x-y), is the cubed root of the first and the cubed root of the second, so in the answer i have (x-1), which is x cubed minus one cubed :) the second factor, (xsquared+xy+ysquared), you take the first number squared, Xsquared, then the first and second one multiplied together, XY, and then the second number squared, Ysquared, so in the answer i have (xsquared+x+1), which is x squared, then x times 1 which is just x, and positive 1, which is negative 1 squared :) x^3 - 1
I assume you mean...,X2 + 11X + 10(X + 1)(X + 10)==============factored
If you mean: 3x squared -11x -20 = 0 Then: x = -5 or x = 4/3
If you mean: x squared -14x +45 then when factored it is (x-9)(x-5)
Because: (9-x)(9-x) = 81-18x+x^2
The discriminant, for what it is worth in an example such as this, is 11.
