Question

if ax^2 + bx + c = 0 has equal root then find the value of c = ?​

Answer 1

Answer:

c is constant so it has no values

Answer 2

Hey buddy here is your answer

ax^2 + bx + c = 0 has equal root

Then,

          −b ± √(b^2 − 4ac)/2a = 1

     => −b ± √(b^2 − 4ac) = 2a

     => ± √(b^2 − 4ac) = 2a + b

     =>b^2 − 4ac = (2a + b)^2

     =>b^2 − 4ac = 4a^2 + b^2 + 4ab

     =>-4ac = 4a^2 + 4ab

     =>-4ac = 4a(a + b)

     =>c = b - a
