Question

factorise 6x3-7x2-14x+15​

Answer 1

Answer:

6x3-7x2-14x+15 is not a perfect cube

Trying to factor by pulling out :

3.2 Factoring: 6x3-7x2-14x+15

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

Group 1: -14x+15

Group 2: 6x3-7x2

Pull out from each group separately :

Group 1: (-14x+15) • (1) = (14x-15) • (-1)

Group 2: (6x-7) • (x2)
