One of the ways to determine what customers want is my doing s survey. A survey would guide you through what they want. One of the ways to do this survey to get accurate answers is through questionnaire's, questionnaire's could be sent through mobile or advert or mails, asking what exactly what the customers want, from the feedback, the owner can predict accurately.

answer; ///i do believe that the correct answer is (

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
