Best ResponseYou've already chosen the best response.0POR=Product Of Root SOR=Sum Of Roots take x^22x+4=0 change it to x^2+2x4=0 (POR)A+B =2 (SOR)AB=4 modify A+B=2 to A=2B then insert to (2B)B=4 expand to 2BB^2 =4 then arrange to B^22B4 then use formula for root got B=3.236 or B=1.236 insert into A=2B finally A=3.236 or A=1.236
