hey mate...


(5x+4)^2 (5x-4)^2

using the properties

(a+b)^2 and (a-b) ^2


(5x^2+4^2+40x)(5x^2+4^2-40x)

(5x^2+16+40x)(5x^2+16-40x)

Question : To simplify :

(5x + 4)(5x + 4)(5x - 4)(5x - 4)

 =  {(5x + 4)}^{2}( {5x - 4)}^{2}

( {5x + 4)}^{2}  =  {(5x)}^{2}  + 2 \times 5x \times 4 +  {4}^{2}

( {5x - 4)}^{2}  =  ({5x)}^{2}  - 2 \times 5x \times4 +  {4}^{2}

Multiplying both the answers :

We get :

 {25x}^{2}  + 40x + 16 \times {25x}^{2}   - 40 + 16

Simplify the answer and you will get the final answer.
