$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Expand ${(3x - 4y)}^{2}$

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

${(3x - 4y)}^{2}$

$= {(3x)}^{2} + {(4y)}^{2} - 2 \times 3x \times 4y$

$= 9 {x}^{2} - 24xy + 16 {y}^{2}$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• $9 {x}^{2} - 24xy + 16 {y}^{2}$

$\star\:\:\:\bf\large\underline\blue{Identity\:Used:-}$

• ${(x - y) }^{2} = {x}^{2} - 2xy + {y}^{2}$
