Question

(2x²y - 3y) (3xy - x)​

Answer 1

x=3−5–√−−−−−−√=6–25–√2−−−−−−√

Since 5=5∗1 and 6=5+1

x=5–√–12–√

Similarly y=5–√+12–√

Alao x2=3−5–√ and y2=3+5–√

Now given expression

=x(1+2y2+y4)−y(1–2x2+x4)

=x(1+y2)2−y(x2–1)2

=5–√–12–√(1+3+5–√)2−5–√+12–√(3−5–√–1)2

=12–√{(5–√–1)(21+85–√)−(5–√+1)(9−45–√)}

=2–√(15+45–√)

I hope you are understand my solution
