${Your\:Answer:}$

_____________________________

=>(0.2x + 10.8y) (0.2x - 10.8y)

Using (A + B) (A - B) = ${a}^{2} - {b}^{2}$

=> ${(0.2x)}^{2} - {(10.8y)}^{2}$

=> $0.04 {x}^{2} - 116.64 {y}^{2}$

Hey mate...

Ur answer is in the attachment....

(0.2x+10.8y)(0.2x-10.8y)

Using the identity (a+b)(a-b) = a²-b²

=(0.2x)²-(10.8y)²

=0.04x²-116.64y²

Hope it helped you....
