Question

If both the zeroes of a polynomial x2+4x+2p are real and equal then find the value of p.

plzz answer fast....it's urgent..

​

Answer 1

p = 2

Explanation:

If both zeroes at equal, they must be the negative half of the second term. As this term is 4,
`-(4)/(2) =-2`. This means that each of the zeroes must be -2. This means that the polynomial must be
`(x+2)^2`

This simplifies to
`x^2+4x+4`

From the intial problem, we can set up an equation and solve for p.
`2p=4\\\\p=2`
