Answer:
-4
Step-by-step explanation:
Since the equation has 2 roots, coefficient of x is equal to b of ax^2+bx+c=0
As we know -b/a is sum of roots in quadratic equation, so having roots as 5 and -1, we get:
-b/a=5-1=4
If we accept a=1, then it appears b=-4
So coefficient of x=-4
The equation will look as: x^2-4x-5=0
