hi mate ,
solution:
Factoring 6x²-x-2
6x² - 4x + 3x - 2
Step-1 : Add up the first 2 terms, pulling out like factors :
2x • (3x-2)
Add up the last 2 terms, pulling out common factors :
1 • (3x-2)
Step-2 : Add up the four terms of step 1 :
(2x+1) • (3x-2)
Which is the desired factorization
Final result :
(3x - 2) • (2x + 1)
3x - 2 = 0 & 2x +1 = 0
x = 2/3 & x = - 1/2
I hope it helps you.
