Answer:
(2x+3)(x-7)
Step-by-step explanation:
✯Hello✯
↪ First you are going to want to equally split the equation into separate brackets - I've done this as (2x^2+3)+(-14x-21)
↪ Further factorise this x(2x+3)
↪ From the other bracet factor -7(2x+3)
↪ they have a common term in which we can use to make new brackets
(2x+3)(x-7)
HOPE THIS HELPS
