Answer:
(3 + 4)2
Step-by-step explanation:
Grouping
1. Use the sum-product pattern
9x² + 24x + 16
9x² + 12x + 12x + 16
2.Common factor from the two pairs
9x² + 12x + 12x + 16
3 (3 + 4) + 4 (3 + 4)
3.Rewrite in factored form
3 (3 + 4) + 4 (3 + 4)
(3 + 4) (3 + 4)
4. Combine to a square
(3 + 4) (3 + 4)
(3 + 4)2
Hope it Helps!
