14 . the sum and the product of two numbers are 25 and 144 respectively , the difference of the number is ?
x + y = 25 xy = 144 ( x - y ) 2 = ( x + y ) 2 â € “ 4 xy ( x - y ) 2 = 625 â € “ 576 = > ( x â € “ y ) = 7 answer : a
subtract(subtract(subtract(power(25, const_2), multiply(144, const_2)), multiply(144, const_2)), subtract(subtract(subtract(subtract(power(25, const_2), multiply(144, const_2)), multiply(144, const_2)), const_4), const_3))
