Question

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

Answer 1

ax² + bx + c = 0

Then the discriminant of this quadratic equation is 0:

So,

Discriminant, D = b² - 4ac

☛ b² - 4ac = 0

☛ 4ac = b²

☛ c = b²/4a

$</p><p></p><p>\huge \sf c = \frac{b^{2}}{4a}</p><p>$

Answer 2

Answer:

c= b^2 /4a hope this would help you
