Question

x³-23X²+142x-120 solved a

Answer 1

x^3 - x^2 - 22x^2 +22x + 120x - 120

=> x^2 (x-1) - 22x(x-1) +120(x-1)

=> (x-1) (x^2 - 22x +120)

=> (x-1)[ x^2 - 12x - 10x +120]

=> (x-1)[ x(x-12) - 10(x-12)]

=> (x-1)(x-10)(x-12)

Answer 2

x^3 - x^2 - 22x^2 +22x + 120x - 120

=> x^2 (x-1) - 22x(x-1) +120(x-1)

=> (x-1) (x^2 - 22x +120)

=> (x-1)[ x^2 - 12x - 10x +120]

=> (x-1)[ x(x-12) - 10(x-12)]

=> (x-1)(x-10)(x-12)
