x3 + 1 = (x + 1)(x2 - x + 1)
The x + 1's cancel out, leaving x2 - x + 1
72000 shares a factor with 40000. This factor is 8000. By having one factor be the same, both of these equations, when divided by the factors NOT shared, will have the same quotient.
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
One million divided by 10 is equal to 100,000. This can be calculated by dividing the number of zeros in one million (six zeros) by the divisor, which is 10. Each zero represents a factor of 10, so when divided by 10, the result is 100,000.

1/6 + 4/15 = 5/30 + 8/30 = 13/30
That becomes x^2 - x + 1
(2x + 1)(4x^2 - 2x + 1)
125x3 + 1 ???????? 53 * x3 + 1 ================?????
It cannot be simplified algebraically and needs to be calculated.
One is the only factor of 50 that is a cube.
(x - 1)(x^2 + x + 1)
This doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (-17 plus or minus the square root of -671) divided by 12x = -1.4166 + 2.158638974498103ix = -1.4166 - 2.158638974498103iwhere i is the square root of negative one.
That doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (-7 plus or minus the square root of -371) divided by 10x = -0.7 + 1.9261360284258224ix = -0.7 - 1.9261360284258224iwhere i is the square root of negative one.
You can. They can be multiplied together or you can divided either one by the other.
That doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (-1 plus or minus the square root of -3) divided by 2.x = -0.5 + 0.8660254037844386ix = -0.5 - 0.8660254037844386iwhere i is the square root of negative one.
Factor the numerator. x+1 is one of its factors (otherwise, it wouldn't be possible to simplify it). Then cancel the identical factors in the numerator and the denominator.
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: (-5 plus or minus the square root of -239) divided by 12.x = -0.416666 repeating + 1.288302069478359ix = -0.416666 repeating - 1.288302069478359iwhere i is the square root of negative one.
