12 times a positive integer is more than its square by 36 , then the positive integer is
"explanation : let the number be x . then , 12 x = x 2 + 36 = > x 2 - 12 x + 36 = 0 = > ( x - 6 ) ( x - 6 ) = 0 = > x = 6 answer : a"
divide(add(12, subtract(power(12, const_2), multiply(36, const_4))), const_2)
