★ QUADRATIC RESOLUTION ★
Standard General quadratic equation :
ax² + bx + c = 0
Conditions for having equal roots :
D = 0
D = discriminant of quadratic = b² - 4ac = 0
b² = 4ac

Hello !!
Given polynomial is ax²+bx+c=0
Now it's zeros will be equal when it's discriminant will be equal to zero
Thus
D = b²-4(a)(c)
Now D = 0
Hence b² = 4ac
or b = 2√ac
