Question

what is (b-2)x(b-7) multiplied

Answer 1

$\qquad \qquad \bf \huge\star \: \: \large{ \underline{Answer} } \huge \: \: \star$

$\qquad❖ \: \sf \: {b}^{2} - 9b + 14$

$\textsf{ \underline{\underline{Steps to solve the problem} }:}$

$\qquad❖ \: \sf \:(b - 2) \sdot(b - 7)$

$\qquad❖ \: \sf \:(b \sdot b) + (b \sdot - 7) - (2 \sdot b) - (2 \sdot - 7)$

$\qquad❖ \: \sf \: {b}^{2} - 7b - 2b + 14$

$\qquad❖ \: \sf \: {b}^{2} - 9b + 14$

$\qquad \large \sf {Conclusion} :$

$\sf \:(b - 2) \sdot(b - 7) = {b}^{2} - 9b + 14$

Answer 2

Answer:

b² - 9b + 14

Step-by-step explanation:

(b - 2) × (b - 7)

= b×b - 7b - 2b + 2×7  (Expand)

= b² - (7b + 2b) + 14  (gather like terms)

= b² - 9b + 14
