Question

Find the value of P so that the equation 3px - 12x+P = 0 has equal roots?

Answer 1

Answer:

Given,

The equation has equal roots.

To find = p

Step-by-step explanation:

We know that if the equation has real and equal roots then,

D = 0

⇒b² - 4ac = 0

⇒ (-12)² - 4(3 p)(p) = 0

⇒144 = 12p²

⇒12p = 12

⇒p = 1

or,

for" p=1", the given equation has real and equal roots

Answer 2

here is ur answer!!

it is given b square -4ac=0

therefore,

-12 square - 3*4*p=0

144-12p=0

-12p=-144

p=12
