Equation of a Plane : Intercept Form

If x, y, z>=,...

Question

If x, y, z > =, then find the value of xy + yz + zx.

Open in App

Solution

You can't simply find xy + yz + zx by knowing just x, y, z range.
You have to be given information about x+y+z and x² + y² + z² for finding xy + yz + zx
If they are given then you can use the formula
(x + y + z)² = x² + y² + z² +2(xy + yz +zx)

However you can get the range of xy + yz + zx if the range of x, y, z are given.

So, as of now this question is wrong and doesn't have a solution.
