Hello:) I need help with 6(b) thank youu in advanced !
( The question is in the pic below )

Answer:
(2y − 7) (4y − 3)
Step-by-step explanation:
From 5(a):
2x² − 5x − 12 = (x − 4) (2x + 3)
Therefore, replacing x with 2y − 3:
2 (2y − 3)² − 5 (2y − 3) − 12
= ((2y − 3) − 4) (2 (2y − 3) + 3)
= (2y − 7) (4y − 6 + 3)
= (2y − 7) (4y − 3)
