You've got a=4
-b/a=sum=-1+6=5 so b=-20
c/a=product=-1*6=-6 so c=-6
Final equation: 4 x 2 − 20 x − 6 = 0

The quadratic equation is 4x² - 20x - 24 = 0 whose roots are-1 and 6.
What is a quadratic equation?
The quadratic equation is defined as a function containing the highest power of a variable is two.
The roots are given in the question, as follows:
-1 and 6
As we know that the standard quadratic equation ax² + b x + c = 0.
Since the leading coefficient of the quadratic equation is 4
So, a = 4
The sum of roots = -b/a
-1 + 6 = -b/4
5 = -b/4
b = -20
The multiplication of roots = c/a
-1 × 6 = c/4
c = -24
So, the quadratic equation is 4x² - 20x - 24 = 0.
