Question

factorise x^3+13x^2+32x+20

Answer 1

Answer:(x + 2) • (x + 1) • (x + 10)

Step-by-step explanation:Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (((x3) +  13x2) +  32x) +  20

Step  2  :

Checking for a perfect cube :

2.1    x3+13x2+32x+20  is not a perfect cube

Trying to factor by pulling out :

2.2      Factoring:  x3+13x2+32x+20

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

Group 1:  x3+13x2

Group 2:  32x+20

Pull out from each group separately :

Group 1:   (x+13) • (x2)

Group 2:   (8x+5) • (4)
