(What is a function?) A function refers to a specific type of mathematical relationship that maps one set of inputs, known as the domain, to a corresponding set of outputs, known as the range. In simpler terms, a function takes an input va...
Since the coefficient of the x2 term is 1, the quadratic can be written as (x−r1)(x−r2)=x2−(r1+r2)x+r1r2. By comparing this with x2−ax+2a, r1+r2=a and r1r2=2a. Plugging the first equation in the second, r1r2=2(r1+r2). Rearranging gives r1r2−2r1−2r...
