Question 153038


{{{w^2-10w+9=0}}} Start with the given equation



{{{(w-9)(w-1)=0}}} Factor the left side 




Now set each factor equal to zero:

{{{w-9=0}}} or  {{{w-1=0}}} 


{{{w=9}}} or  {{{w=1}}}    Now solve for w in each case



So the solutions are


 {{{w=9}}} or  {{{w=1}}}


This means that the answer is b) x = 1, 9 only
