Question 681477
one number is equal to the square of another.
x = y^2
:
 Find the numbers if both are positive and their sum is 12
x + y = 12
replace x with y^2, you have a quadratic equation
y^2 + y - 12 = 0
Factors to
(y+4)(y-3) = 0
The positive solution is all they want here
y = 3
then
x = 3^2
x = 9
;
they add up to 12
