Question

Answer is -16.....How to do the steps?

Answer 1

Product of roots
Let x and y be the roots of given equation.

y+z=-b/a (sum of roots)

z×y= c/a(product of roots)

where "a" is coefficient of x^2 and "b" of x and "c" a constant.
In the given equation is a=1,b=h+4 c=-h^2
so product is given by

y×z= -h^2/1= product is -h^2
