Since the quadratic has roots a and b, this means it can be fatored as 2(x-a)(x-b)=0. Expanding this out we get 2x^2-2(a+b)x+2ab=0 and matching the coefficients for the terms x^1 and x^0 we get a+b=-4 and...

There are four DNA nucleotides: Adenine, Cytosine, Thymine and Guanine. They are each made up of a nitrogenous base, deoxyribose sugar, and a phosphate group, and the four nucleotides differ in the struct...
