Question

If ax^2+bx+c=0 has equal roots,what is the value of c

Answer 1

Question:

If ax²+bx+c=0 has equal roots find the value of c.

Solution:

Given that the zeros of the quadratic equation are equal,i.e.the D is zero

Here,

D=B²-4AC

→0=b²-4ac

→b²=4ac

→c=b²/4a

_______________________

Thus,c=b²/4a
