SOLUTION: Find the sum and products of the roots of the equation: 2 y square -10y + 7 = 0

Vieta's theorem says that for this quadratic equation the sum of the roots is  
the coefficient at y, divided by the coefficient at y^2 and taken with the opposite sign

    the sum of the roots = -  = 5.


This theorem also says that the product of the roots is the constant term, 
divided by the coefficient at y^2

    the product of the roots = .
