Question

Q1 square + Q2 square - 6 Q1 Q2 = 0 .find Q1 upon Q2

Answer 1

Hey mate,

ATQ,

Q1^2 + Q2^2 - 6Q1Q2 = 0

So just send 6Q1Q2 to other side,
Then divide,

Q1/Q2 + Q2/Q1 = 6

So let Q1/Q2 = a

Then a+ 1/a = 6

a^2 - 6a +1 =0

a = 6 +- root(32)/2

So ratio = - 3 +- 2 root (2)

Hope this helps you out!
