Step-by-step explanation:
[tex] {(3x + y)}^{2} \\ = {(3x)}^{2} + {y}^{2} + 2 \times 3x \times y \\ = 9 {x}^{2} + {y}^{2} + 6xy[/tex]
ʜᴇʀᴇ'ꜱ yᴏᴜʀ ᴀɴꜱᴡᴇʀ
ꜱɪᴍᴩʟɪꜰy → (3x +y)²
ʟᴇᴛ'ꜱ ᴜꜱᴇ ᴛʜᴇ ɪᴅᴇɴᴛɪᴛɪᴇꜱ ʜᴇʀᴇ:
✎ (a + b)² → a² + 2ab + b²
ꜱɪᴍɪʟᴀʀʟy,
✎ (3x +y)² → 3x² + 2 (3x + y) + y²
ʟᴇᴛ'ꜱ ꜱɪᴍᴩʟɪꜰy
✎ 3x² + 2 (3x + y) + y²
9x² + 6xy + y²
HOPE THIS HELPS ✌
