Dear kamleshlet equation isax2 +bx+c=0 and root are x1 and x2 and a,b,c are integerx1 +x2 =-b/a give x1 and x2 are prime ,only possible if a=1so x1 +x2 =-b/a and x1*x2 =calso givena+b+c =prime numberor 1+b+c=prime numberput vale of b and c1-(x1+x2) +x1*x2 =prime number(x1-1)(x2-1)=prime numberonly possible if one bracket is equal to 1ie x1=2and x2=3(prime number)so sum x1+x2=2+3=5Please feel free to post as many doubts on our discussion forum as you can.
