Let . Let the real roots of and real roots of .The least value of . The least value of g(x) occurs at x = 7/12.
The least value of g(x) is
The least value of f(x) is
Therefore, the least value of
The least value of g(x) occurs at
The value of b2 is
The least value of g(x) occurs at
The product of the roots of g(x) = 0 are
