Question

If p-1/p = 4 Find (p+1/p)²​

Answer 1

4

Explanation:

`(p - 1)/(p) = 4`

Solve for p.

The numerator. difference has to be 4 times the answer of the denomiator.

So we can say

`p - 1 = 4p`

Solve for p

`- 1 = 3p`

`p = - (1)/(3)`

Now plug this in for the other formula.

`( ( - (1)/(3) +1)/( (1)/(3) ) ) {}^(2) = 2 {}^(2) = 4`

So
