1.	2. If two roots of the quadratic equation ax+bx+c = 0 ( a +0 ) are equal in magnitude butopposite in sign, then the value of 'b'is
Answer» 0 is the correct answer sir..... let p and -p are the two roots.ax^2+bc+c=0sum of roots= -b/ap+(-p)=-b/a0= -b/a-b=0b= 0 let p and -p are the root of eachax^2+bx+c=0p+(-p)= -b/a0= -b/a-b=0b= 0 b=0 is the correct answer

Answer»

0 is the correct answer sir.....

let p and -p are the two roots.ax^2+bc+c=0sum of roots= -b/ap+(-p)=-b/a0= -b/a-b=0b= 0

let p and -p are the root of eachax^2+bx+c=0p+(-p)= -b/a0= -b/a-b=0b= 0

b=0 is the correct answer
