Question

If 2 roots of 2x^2 + bx + c = 0. Are reciprocal of each other then find the value of c.

Answer 1

Ans : let roots be @ and 1/@

Product of zeroes = c/2
=> @ × 1/@ = c/2
=>1 = c/2
=>c =2×1

Value of c is 2

Hope it helps..!!

Answer 2

Answer:

Step-by-step explanation:

Let the roots be (x)&(1/x) i.e., @&ß (roots)

Here, a=2, b=b, c=c

@ß = c/a. (product of roots)

x(1/x) = c/2

1 = c/2

C = 2
