To find: Explain why an equation having no actual solution gives a solution sometimes.
Answer to Problem 128AYU
An equation having no actual solution gives a solution sometimes.
Explanation of Solution
Given information:
An equation
Calculation:
Solve the equation for
So it does appear that the solution to equation
Notice that in order to solve the equation we had to get rid of denominators of the fractions by multiplying both sides of the equations by the denominator
By doing this we remove the restriction that the fractions in the equation are undefined when
This is why it appears that the solution is
Therefore,. an equation having no actual solution gives a solution sometimes.
