when it is prime, we just state "prime" and do not attempt to factor. Now if it said, solve then we solve using the quadratic formula

correct, if the instructions were to factor write "prime" if the instructions were to solve then use the quadratic formula

It's prime! Applying quadratic formula, we get: a^2 – 5*a – 20 = 0 a = 1, b =  5, c =  20 b^2  4*a*c = 25  4*1*(  20) = 105 a1 = (  (  5) + sqrt(105))/2 = 5/2 + (1/2)*sqrt(105) a2 = 5/2  (1/2)*sqrt(105)
