Since b#3,this implies (4+2/b) = 0 and thus 4=  2/b or b = 1/2 Posted from my mobile device

Given \(b\neq{3}\) , means \(b3\neq{0}\) So, \(4+\frac{2}{b} = 0\) \(b = \frac{1}{2}\) Answer = C

If (b3)(4+ 2/b) = 0 and \(b \neq {3}\), then b= a) 8 b) 2 c)1/2 d) 1/2 e) 2 I got the solution through substituting the answers, but could someone show me how to reduce the factors to get rid of the fraction in the second factor? How do I solve it algebriacely?

(b  3)(4 + 2/b) = 0
b = 3 or 2/b = 4
Its given \(b \neq {3}\)
So, 2/b = 4 > b = 2/4 = 1/2
Answer: C

This is the Zero Product Property. It says that, if: a × b = 0 then a = 0 or b = 0 or both equal zero So, in \(\left( b3 \right) \left( 4+\cfrac { 2 }{ b } \right) =0\): \(b3=0\) and \(4+\cfrac { 2 }{ b } =0\) Since \(b\neq 3\) then \(4+\cfrac { 2 }{ b } =0\rightarrow \left( 4+\cfrac { 2 }{ b } =0 \right) b\rightarrow 4b+2=0\rightarrow 4b=2\rightarrow b=\cfrac { 2 }{ 4 } \rightarrow b=\cfrac { 1 }{ 2 }\)
