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}} \displaystyle \Rightarrow ac\times ac-ac\times ad-bd\times bc+bd\times ad \displaystyle \Rightarrow ac\times bc-ac\times ad-bd\times bc+bd\times ad \displaystyle \Rightarrow ac(bc-ad)-bd(bc-ad)## \displaystyle \Rightarrow (bc-ad)(ac-bd) [Answer]
