x is a positive number which when increased by 17 is equal to 60 times the reciprocal of the number . find value of x ?
let the number be x . then , x + 17 = 60 x x 2 + 17 x - 60 = 0 ( x + 20 ) ( x - 3 ) = 0 x = 3 a
divide(add(negate(17), sqrt(subtract(power(17, const_2), multiply(const_4, multiply(const_1, negate(60)))))), const_2)
