Question

find the product of

(3x-2y)^2 by using identity.​

Answer 1

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

${(3x)}^{2} - 2.3x.2y + {(2y)}^{2}$

$9 {x}^{2} - 12xy + 4 {y}^{2}$

Answer 2

Answer:

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

let's substitute this from identity

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

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

$= 9x {}^{2} - 12xy + 4y {}^{2}$
