Question

Factorize by splitting the middle term. 3x^2-2x-8

Answer 1

Step-by-step explanation:

Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 4

3x2 - 6x + 4x - 8

Step-4 : Add up the first 2 terms, pulling out like factors :

3x • (x-2)

Add up the last 2 terms, pulling out common factors :

4 • (x-2)

Step-5 : Add up the four terms of step 4 :

(3x+4) • (x-2)

Which is the desired factorization

Final result :

(x - 2) • (3x + 4)
