Let x = the number.
= square of the number
= difference between a number and its square
= average of a number and it's square (add together and divide by 2)
The equation should look like this:
Multiply both sides of the equation by 2:
Set equal to zero, by subtracting x and
from each side:
Factor out the common factor of x:
x= 0 or x= 3
There are two solutions.
x=0: The square is 0. The difference of the number and its square is zero, and the average of 0 and its square is also 0.
x= 3: The square is 9. The difference of the number and its square is 6, and the average of the number and its square is
Both answers check.
