Question

factorise x cube minus 23 x square + 142 X - 120​

Answer 1

Answer:

x^3 - 23x^2 + 142x - 120

The common factor is (x-1)

so, x^2(x-1) -22x(x-1) +120(x-1)

or, (x-1) (x^2 - 22x + 120)

or, (x-1) (x^2 -10x -12x + 120)

or, (x-1) [x(x-10) -12(x-10) ]

or, (x-1) (x-10) (x-12)

this is the solution of your question
