Question

Expand using identities (0.3x+0.
3y)(0.3x-0.3y)

Answer 1

$by \: using \: the \: identity \: of \\ \\ = (a {}^{2} - {b}^{2} ) \\ \\ we \: get \\ \\ - - - - - \\ \\ = (0.3x + 0.3y)(0.3x - 0.3y) \\ \\ = ( {(0.3x)}^{2} - {(0.3y)}^{2} ) \\ \\ = (0.09 {x}^{2} - 0.09 {y}^{2} ) \\ \\ = 0.09 {x}^{2} - 0.09 {y}^{2} \\ \\ - - - - - - \\ \\ {\mathfrak{Here is your answer..
