# How to solve; ab * (c ^ 2 + d ^ 2) – a ^ 2 * c * d – b ^ 2 * c * d

Welcome to my article How to solve; ab * (c ^ 2 + d ^ 2) – a ^ 2 * c * d – b ^ 2 * c * d. This question is taken from the simplification lesson.
The solution of this question has been explained in a very simple way by a well-known teacher by doing addition, subtraction, and fractions.
For complete information on how to solve this question How to solve; ab * (c ^ 2 + d ^ 2) – a ^ 2 * c * d – b ^ 2 * c * d read and understand it carefully till the end.

Let us know how to solve this question How to solve; ab * (c ^ 2 + d ^ 2) – a ^ 2 * c * d – b ^ 2 * c * d

First write the question on the page of the notebook,

## How to solve; ab * (c ^ 2 + d ^ 2) – a ^ 2 * c * d – b ^ 2 * c * d

On writing this question in this way,

\displaystyle \Rightarrow ab\times ({{c}^{2}}+{{d}^{2}})-{{a}^{2}}\times c\times d-{{b}^{2}}\times c\times d

\displaystyle \Rightarrow ab\times {{c}^{2}}+ab\times {{d}^{2}}-{{a}^{2}}\times c\times d-{{b}^{2}}\times c\times d

\displaystyle \Rightarrow ab{{c}^{2}}+ab{{d}^{2}}-{{a}^{2}}cd-{{b}^{2}}cd

\displaystyle \Rightarrow ab{{c}^{2}}-{{a}^{2}}cd-{{b}^{2}}cd+ab{{d}^{2}}
