Question

If the difference of the roots of the equation
x2-bx+c=0 be 1, then:
(a) b2 - 4c + 1 = 0
(b) b2 + 4c = 0
(d) b2 - 4c = 0
(c) b² - 4e-1=0​

Answer 1

Answer:

d)

Step-by-step explanation:

if it is equal to zero then b²-4ac=0

then b²-4c=0

Answer 2

Answer:

d)

Step-by-step explanation:

If it is equal to zero then b2-4ac=0,

Then b2-4ac= 0
