How do you factor 9x cubed plus 18x squared minus x minus 2?
(x + 2)(3x - 1)(3x + 1)
X cubed minus 8 equals zero but the answer is 2 comma negative 1 plus and minus square root 3. How did they get this as the Answer?
x 3-8
What is x cubed minus 4x squared plus x plus 6 when fully factorized?
x3 - 4x2 + x + 6 = (x + 1)(x - 2)(x - 3)
How do you factor the expression x cubed minus x squared plus x minus 1?
x^3 - x^2 + x - 1 = (x^3 - x^2) + (x - 1) = x^2(x - 1) + (x - 1) = (x -1)(x^2 + 1)
What is x minus 1 cubed?
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
