Question

factorize the numerator and simplify:bsq+8b+7upon(b+7)​

Answer 1

Answer:

$\green{b + 1 }$

Step-by-step explanation:

$\frac{ {b}^{2} + 8b + 7 }{b + 7} \\ \\ = \: \frac{ {b}^{2} + b + 7b + 7 }{b + 7} \\ \\ = \: \frac{b(b + 1) + 7(b + 1)}{b + 7} \\ \\ = \: \frac{(b + 7)(b + 1)}{b + 7} \\ \\ = \: \frac{ \cancel{(b + 7)} \: \: (b + 1)} { \cancel{b + 7}} \\ \\ = b + 1$
