Question

evaluate using identities (3x-2y)^2​

Answer 1

⏩we know that

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

then ,

$(3x - 2y) {}^{2} = 9x {}^{2} + 4y {}^{2} - 12xy$

⏩i hope it help you

Answer 2

Heya!❤️

By using identity:

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

Let's consider 3x as a and 2y as b

So,

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

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

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

Hope this helps
