In class 8th mathematics classroom, Rashmi solved the problem in following way. To prove \frac{ac\:−2b^{2}}{b} = \frac{c^{2}−2bd}{d} , if \frac{a}{b} = \frac{c}{d} is given, she starts from\frac{ac\:−2b^{2}}{b} = \frac{c^{2}−2bd}{d} and gets the answer \frac{a}{b} + \frac{c}{d}. Which method is Rashmi applying in her class?

Correct Answer is : Analytical method

In class 8th mathematics classroom, Rashmi solved the problem in following way. To prove

\;{ac\:−2b^{2}}/{b} = \;{c^{2}−2bd}/{d}

, if

\;{a}/{b} = \;{c}/{d}

is given, she starts from

\;{ac\:−2b^{2}}/{b} = \;{c^{2}−2bd}/{d}

and gets the answer

\;{a}/{b} + \;{c}/{d}

.
