Answer:
ᴡᴇ ᴡɪʟʟ ᴜꜱᴇ ᴛʜᴇ ɪᴅᴇɴᴛɪᴛy \[\ʟᴇꜰᴛ( ᴀ + ʙ \ʀɪɢʜᴛ)\ʟᴇꜰᴛ( ᴀ - ʙ \ʀɪɢʜᴛ) = ᴀ^2 - ʙ^2\] ɪɴ ᴛʜᴇ ɢɪᴠᴇɴ ᴇxᴩʀᴇꜱꜱɪᴏɴ ᴛᴏ ꜰɪɴᴅ ᴛʜᴇ ᴩʀᴏᴅᴜᴄᴛ.
\[\ʟᴇꜰᴛ( \ꜰʀᴀᴄ{4x}{5} - \ꜰʀᴀᴄ{3y}{4} \ʀɪɢʜᴛ)\ʟᴇꜰᴛ( \ꜰʀᴀᴄ{4x}{5} + \ꜰʀᴀᴄ{3y}{4} \ʀɪɢʜᴛ)\]
\[ = \ʟᴇꜰᴛ( \ꜰʀᴀᴄ{4x}{5} \ʀɪɢʜᴛ)^2 - \ʟᴇꜰᴛ( \ꜰʀᴀᴄ{3y}{4} \ʀɪɢʜᴛ)^2 \]
\[ = \ꜰʀᴀᴄ{16 x^2}{25} - \ꜰʀᴀᴄ{9 y^2}{16}\]
