best des
ax2 + bx + c = 0
Where, b = alpha + beta and c = alpha * beta
Therefore,
ax2+ (alpha+beta)x + alpha*beta = 0
Here,
alpha*beta = 6
According to question,
alpha = beta
So,
alpha*alpha = 6
or, alpha2 = 6
or, alpha = √6
Again,
p = alpha + beta
or, p = alpha + alpha
or, p = 2alpha
or, p = 2√6 = √4 * √6 = √24
