Answer:
p = 4
Step-by-step explanation:
Using the discriminant b² - 4ac to determine the nature of the roots.
If b² - 4ac = 0 then real and equal roots
Given
px² - 4x + 1 = 0
with a = p, b = - 4 and c = 1, then
(- 4)² - 4p = 0
16 - 4p = 0 ( subtract 16 from both sides )
- 4p = - 16 ( divide both sides by - 4 )
p = 4
Answer:
for repeated roots ,
b²-4ac=0
16-{4p}=0
p=4
