8x2-39x+45 = (8x-15)(x-3) when factored
xsquared minus x minus 72
The expression "xsquared minus 10x" can be written mathematically as ( x^2 - 10x ). This is a quadratic expression and can be factored as ( x(x - 10) ). It represents a parabola that opens upwards and has zeros at ( x = 0 ) and ( x = 10 ).
100 minus 45 x 5 is equal to -125.
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
It is minus one half.
