18 times a positive integer is more than its square by 80 , then the positive integer is
"explanation : let the number be x . then , 18 x = x 2 + 80 = > x 2 - 18 x + 80 = 0 = > ( x - 10 ) ( x - 8 ) = 0 = > x = 10 or 8 answer : b"
divide(add(18, subtract(power(18, const_2), multiply(80, const_4))), const_2)
