Wow! Great question.
Read in chunks. Stem is hard to understand but the que is too easy.
(the product of the factors of) twice the sum of the roots of the equation
\(2x^2 - 4x - 6 = 0\)
\(x^2 - 2x - 3 = 0\)
Roots are : \(3\) & \(-1\)
Sum of roots : \(2\)
Twice the sum of roots : \(4\)
We are asked the product of factors oftwice the sum of roots.
So product of factors of \(4\)
Factors of \(4\) : \(1 , 2 , 4\)
Product = \(1 * 2 * 4 =\) \(8\)
