Question

# Show the conjecture is false by finding a counterexample. If the product of two numbers is positive, then the two numbers must both be positive.

Hint:

### Take 2 numbers and then check.

## The correct answer is: Hence we disproved the conjecture

### Complete step by step solution:

Here, take 2 negative numbers to be - 2 and - 5

Then product of - 2 and - 5 is (- 2) (- 5) = 10 which is a positive number.

This implies that the product of 2 negative numbers can also be positive.

Hence we disproved the conjecture.
