When the first two terms and the last two terms are grouped, the common binomial factor is 6x – 7
Data obtained from the question
- 30x² – 35x + 54x – 63
- Common factor =.?
How to determine the common factor
30x² – 35x + 54x – 63
Group the first two and the last two terms
(30x² – 35x) + (54x – 63)
Factorise
5x(6x – 7) + 9(6x – 7)
Common factor => 6x – 7
Therefore, we can conclude that the common binomial factor in the expression is 6x – 7
