I was doing an exmple and thinking about my expected retrun value to kow if my function worked.
However I don't think any value could test true therefore my function would always be false. I do need to double check though as my math is rusty. But you cannot square a number and have it retun negative can you? This is my working. ;;; equation : number --> boolean ;;; to determine whether n is true for the equation (2 - n(squared) = 102) (define (forn x) (= (- 2 (* x x) ) 102))
