let a positive number be x
if the square of a positive number is decrease by five times the number, the result is 14, then we have
x%5E2-5x=14....solve for x
x%5E2-5x-14=0
x%5E2%2B2x-7x-14=0
%28x%5E2%2B2x%29-%287x%2B14%29=0
x%28x%2B2%29-7%28x%2B2%29=0
%28x-7%29%28x%2B2%29=0
solutions:
x=7
or
x=-2-> since you need positive number, disregard negative solution
so, your number is 7
