Question

3x³+5x²-16x-2 factorise​

Answer 1

Step-by-step explanation:

((3 • (x3)) + 5x2) - 16x) - 2

(3x3 + 5x2) - 16x) - 2

3x3+5x2-16x-2  is not a perfect cube

answer

Factoring:  3x3+5x2-16x-2 

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

Group 1:  -16x-2 

Group 2:  3x3+5x2 

Pull out from each group separately :

Group 1:   (8x+1) • (-2)

Group 2:   (3x+5) • (x2)
