Question

factorise x³-6x²-13x+42​

Answer 1

Step-by-step explanation:

Factoring: x3-6x2-13x+42

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: -13x+42

Group 2: -6x2+x3

Pull out from each group separately :

Group 1: (-13x+42) • (1) = (13x-42) • (-1)

Group 2: (x-6) • (x2)
