First is -1 and 4, second should be no solution and the third is 2 and 6
Answer:
4
Step-by-step explanation:
Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.
The square of 4 and 2 adds up to 20!
4 square is 16.
2 square is 4
So 16+4=20
