Question

expand the following.:(√3x-√2y-7)sq

Answer 1

${( \sqrt{3}x - \sqrt{2}y - 7) }^{2} \\ = 3 {x}^{2} + 2 {y}^{2} + 49 + 2( \sqrt{3} x - \sqrt{2} y - 7) \\ 3 {x}^{2} + 2 {y}^{2} + 49 + 2 \sqrt{3} x - 2 \sqrt{2} y - 14 \\ 3 {x}^{2} + 2 {y}^{2} + 2 \sqrt{3} x - 2 \sqrt{2}y + 35$

Answer 2

hey mate

it's...

=. (3^1/2x-2^1/2y-7)^2

=. 3x^2+2y^2+49-2×2^1/2×3^1/2xy+14×2^1/2y-14×3^1/2x

I hope it will help you
