Question

if b2-4ac=0 then c=0?
​

Answer 1

Answer:

no

Step-by-step explanation:

if b²-4.a.c=0 , then it means 'd' is equal to 0 and the roots are going to be real and equal (the eqn is a perfect square).

I dunno, who told you the above statement, aah lemme clear this with an example.

x²-4x+4

b²-4ac

16-4.1.4

16-16=0

see here d=0 but c≠0 and the eqn is in it's simplest form..

Hope my answer would help you

Thank you
