**MathMate**, Saturday, June 30, 2012 at 8:52am4x²+5x+γ=4(x-k)(x-1/k)

=4x²-4(k+1/k)+1

Equate coefficients of terms:

for x²: 4=4

for x: -4(k+1/k)=5

for constant term: γ=1

So the equation is:

4x²+5x+1=0

(4x+1)(x+1)=0

**Reiny**, Saturday, June 30, 2012 at 9:08amlet the roots be p and 1/p

We know that for ax^2 + bx + c = 0

the sum of the roots = -b/a

product of roots = c/a

so in our case, product of the roots = gamma/4

but the product of roots = p(1/p) = 1

so

gamma/4 = 1

gamma = 4
