Question

HELP ASAP PLEASE its due tomorrow!!
d^2 - c^3
d = 8 and c = 5

Answer 1

c = a

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.

Answer 2

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