SOLUTION: If xy = a, xz = b, and yz = c, and none of these quantities is 0, then what is the x^2

SOLUTION: If xy = a, xz = b, and yz = c, and none of these quantities is 0, then what is the x^2 - y^2 + z^2?

Question 1064767: If xy = a, xz = b, and yz = c, and none of these quantities is 0, then what is the x^2 - y^2 + z^2?

(1)  
(2)  
(3)  
(4)     <--mult. equals by equals, (1) and (2)
(5)     <--mult. equals by equals, (1) and (3)
(6)     <--mult. equals by equals, (2) and (3)
(7)     <--div. both sides of (4) by yz
(8)     <--div. both sides of (5) by xz
(9)     <--div. both sides of (6) by xy
(10)
