Question

factories the given Q:-
x³-23x²+142x-120

Answer 1

x^3-12x^2-11x^2+132x+10x-120
x^2(x-12)-11x(x-12)+10(x-12)
(x-12)(x^2-11x+10)
(x-12){x^2-10x-x+10}
(x-12){x(x-10)-1(x-10)}
(x-12)(x-10)(x-1)

Answer 2

Answer:

Step-by-step explanation:

x^3-12x^2-11x^2+132x+10x-120

x^2(x-12)-11x(x-12)+10(x-12)

(x-12)(x^2-11x+10)

(x-12){x^2-10x-x+10}

(x-12){x(x-10)-1(x-10)}

(x-12)(x-10)(x-1)
