Question

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

Answer 1

b² - 9b + 14

Explanation:

(b - 2) × (b - 7)

= b×b - 7b - 2b + 2×7 (Expand)

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

= b² - 9b + 14

Answer 2

`\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`
