The product of two integers is -135. If one number is -15. find the other integer.

Represent the following situations in the form of quadratic equation: The product of two consecutive positive integers is 306. We need to find the integers.

There are four unknown numbers. The mean of the first two numbers is 4 and the mean of the first three is 9. The mean of all four number is 15, if one of the four number is 2 find the other numbers.

The mean of five positive integers is twice their median. If four of the integers are 3, 4, 6, 9 and median is 6, then find the fifth integer.

The product of three integers is -3.Determine all the possible values for the three factors.
