Question

Find the difference between alpha and beta ?​

Answer 1

sorry i do not know i pass the answer

Answer 2

Answer:

Step-by-step explanation:

For a quadratic eqn ax^2 + bx + c

sum of roots = -b/a

product of roots = c/a

Here,

4x^2 - 20x -p^2 = 0

alpha + beta = -(-20) / 4 = 5

alpha * beta = -p^2 /4

Now,

(a-b)^2 = (a+b)^2 - 4ab

(alpha - beta )^2 = (5)^2 - 4 * -p^2/4

                           = 25 + p^2

(alpha-beta) = root (25 + p^2)

Your answer is A

HOpe it helps:-)
