Question

factorise 2x cube -3x square -17x+30​

Answer 1

Answer:

Step-by- 2x3+x2-61x+30=0  

Three solutions were found :

x = 5

x = -6

x = 1/2 = 0.500

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 ((2x3 +  x2) -  61x) +  30  = 0  

Step  2  :

Checking for a perfect cube :

2.1    2x3+x2-61x+30  is not a perfect cube  

Trying to factor by pulling out :

2.2      Factoring:  2x3+x2-61x+30  

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

Group 1:  -61x+30  

Group 2:  2x3+x2  

Pull out from each group separately :

Group 1:   (-61x+30) • (1) = (61x-30) • (-1)

Group 2:   (2x+1) • (x2)
