Question

For what values of p, the roots of the equation x

2

+4x + p=0 are real and equal​

Answer 1

alpha+beta= -7

alpha.beta=2

then the eqn will be

x²-(alpha+beta)x+(alpha.beta)=0

x²+7x+2=0.

Answer 2

Answer:

4

Step-by-step explanation:

x 2 +4x + p=0

=>  roots are real and equal​ => b² - 4ac = 0

a =1, b= 4, p =c

from formula, 4² - 4(1)p = 0

4 - p = 0

p = 4
