<u>Formula</u>

Use the following formula.


The expression p²+2p+4 has the discriminant less than 0 ( D < 0 ).
Thus, remove the expression and leave only p-2

<u>Substitution</u>
The most obvious number that multiplies itself three times and equal 8 is 2.
Substitute p = 2

The equation is true, thus 2 is the answer.
Answer:
2
