FINDING QUADRATIC EQUATION GIVEN SUM AND PRODUCT OF ROOTS CONDITION FOR EQUAL ROOTS, REAL ROOTS AND NO ROOT

We recall that if ax² + bx + c = 0, where a, a and c are constants such that a ≠ 0, then,

x  =-b+b2-4ac2a   or x = -b-b2-4ac2a

Suppose we represent these distinct roots by α and β; thus:

α = -b+b2- View More
