Answer 2

$\huge\mathfrak{\color{orange}{\underline {\underline{Answer❀}}}}$

${y}^{2} - 6y + 9$

${y}^{2} - 2 \times y \times 3 + {3}^{2}$

$\bold\red {Using\: Identity}$

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

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

$(y - 3)(y - 3)$

${\large{\boxed{\purple{✏More\: Identities}}}}$

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

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

$(x + a)(x + b) = {x}^{2} + (a + b)x + ab$

${(a + b)}^{3} = {a}^{3} + {b}^{3} + 3ab(a + b)$

hope it helps you.......
