The problem asks for the sum of the roots of the quadratic equation 2m2−16m+8=0,Dividing each side of the equation by 2 gives m2−8m+4=0.If the roots of m2−8m+4=0 are s1 and s2 then the equation can be factored as m2−8m+4=(m−s1)(m−s2) gives −8=−s1−s2, or s1+s2=8 Alternatively, one can apply the quadratic formula to either 2m2−16m+8=0 or m2−8m+4=0.The quadratic formula to either 2m2−16m+8=0 or m2−8m+4=0.The quadratic formula gives two solutions ,4−2√3 and 4+2√3 whose sum is 8 Choices A, B, and C are incorrect and may result from calculation errors when applying the quadratic formula or a sign error when determining the sum of the roots of a quadratic equation from its coefficients
