Answer 1

Answer:

Hello mate✌✌✌

$3 {b}^{2} + 16b + 20 \\ 3 {b}^{2} + 6b + 10b + 20 \\ 3b(b + 2) + 10(b + 2) \\ (3b + 10)(b + 2)$

Hope it helps✌✌✌

Answer 2

Step-by-step explanation:

$3 {b}^{2} + 16b + 20 \\ here... \\ a = 3 \\ b = 16 \\ c = 20 \\ \\ b = \frac{ - b \: + \: or \: - \sqrt{ {b}^{2} - 4ac } }{2a} \\ \: \: \: = \frac{ - 16 \: + \: or \: - \sqrt{256 - 240} }{6} \\ \: \: \: = \frac{ - 16 + \: or \: - 4}{6} \\ b = \frac{ - 16 + 4}{6} \: \: \: or \: \: \: b = \frac{ - 16 - 4}{6} \\ b = - 2 \: \: \: \: \: \: \: \: \: \: \: \: \: \: or \: \: \: b = \frac{ - 10}{3}$
