Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and -2 2x2 - 3x - 2x - 3
Step-4 : Add up the first 2 terms, pulling out like factors : x • (2x-3) Add up the last 2 terms, pulling out common factors : 1 • (2x-3) Step-5 : Add up the four terms of step 4 : (x-1) • (2x-3) Which is the desired factorization

Answer:
(2x-3)•(x-1)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 2 • 3 = 6
Step-2 : Find two factors of 6 whose sum equals the coefficient of the middle term, which is -5 .
-6 + -1 = -7
-3 + -2 = -5 That's it
2x2 - 3x - 2x - 3
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (2x-3)
Add up the last 2 terms, pulling out common factors :
1 • (2x-3)
Step-5 : Add up the four terms of step 4 :
(x-1) • (2x-3)
