Question

2x^2+3y^2 varies xy p.t x+y varies x-y​

Answer 1

Answer:

Step-by-step explanation:

first did this and then I remembered the part 1. and the result is unexpected. I got the value of m!!Divide (1) by y2,2(x/y)2+3=5k(x/y)…(2) Divide (1) by x2,2+3(y/x)2=5k(y/x)…(3) Solving (2) and (3) for x/y and y/x respectively, we get x/y=5k+−25k2–24−−−−−−−√4…(4) and y/x=5k+−25k2–24−−−−−−−√6…(5). From (4) and (5),  5k+−25k2–24−−−−−−−√4=65k+−25k2–24−−−−−−−√  or 24=(5k+−25k2–24−−−−−−−√)2 which gives value of (5k+−25k2–24−−−−−−−√)=+−24−−√ giving x/y=+−24−−√/4=+−6–√/2 which gives value of m of (1) as +−2/6–√
