Answer:

(b + 4)² + 4(b + 4) — 21

(b + 4)(b + 4) + 4(b + 4) - 21

(b + 4)(b + 4) + 4(b + 4) - 21

b(b + 4) + 4(b + 4) + 4(b + 4) - 21

b(b + 4) + 4(b + 4) + 4(b + 4) - 21 b² + 4b + 4(b + 4) + 4(b + 4) — 21

b² + 4b + 4(b + 4) + 4(b + 4) - 21

b² + 4b + 4b + 16 + 4(b + 4) - 21

b² + 4b + 4b + 16 + 4(b + 4) − 21

b^ +8b+16+4(b+4)–21

b^ +8b+16+4(b+4) – 21

b² + 8b+ 16 + 4b + 16-21

b² + 8b+ 16 + 4b + 16-21

b² + 8b+ 11 + 4b

b² + 8b+ 11 + 4b

b²+12b+11.
