Question

Complete the table by determining the appropriate pair of integers whose product and sum are listed. [1 mark each]

Answer 1

This shows that the required numbers are 2 and 4 for the first column

This shows that the required numbers are 3 and 7 for the third column

Hence the two numbers are -1 and -3 for the third column

Explanation:

From the taken, we need to find two numbers whose their product will give 8, 21 and 3 and their sum will give 6, 10 and -4 respectively

If the product is 8 and sum is 6, then the required values area;

`Product = (2* 4) = 8\\Sum = (2 + 4) = 6\\`

This shows that the required numbers are 2 and 4 for the first column

Similarly for the second column;

`(7 * 3) = 21\\(7 + 3) = 10`

Hence the two numbers are 7 and 3 for the second column

Similarly for the third column;

`(-1 * -3) = 3\\(-1 + (-3)) = (-1-3) = -4\\`

Hence the two numbers are -1 and -3 for the second column
