Answer 2

$\displaystyle\huge\red{\underline{\underline{Solution}}}$

$\longmapsto \:$FORMULA TO BE IMPLEMENTED

We are aware of the identity that

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

$\longmapsto \:$QUESTION

Find the value of p if xyp = (3x + y)²– (3x – y)²

$\longmapsto \:$CALCULATION

$xyp = (3x + y)² \: – \: (3x – y)²$

$\implies \: xyp = (3x + y + 3x – y)(3x + y - 3x + y) \: \: \: using \: the \: above \: mentioned \: identity$

$\implies \: xyp = 6x \times 2y$

$\implies \: xyp = 12xy$

$\therefore \: p = 12 \:$
