    Answer:

    c = a

    Step-by-step explanation:

    Let k be one of the root of the given equation.

    According to the problem,

    1/k will be the other root of the given equation.

    We know that, product of the roots of the equation = c/a.

    Therefore, k × 1/k = c/a.

    or, 1 = c/a.

    or, a = c [multiplying a on both sides].

    The roots of the equation ax2 + bx + c = 0 will be reciprocal if a = c.

    Therefore, a = c or c = a.

    If d= 8, and c= 5, then:
    8^2= 64
    5^3= 125
