solving quadratic equations

Example

above is a quadratic equation. it is when you make an input output box. here is an example below

the rule is: 9*4+x^3=y and n=4. when you solve one you replace x with 4

                    9*4+4^3=?

then you remember,PEMDAS but only the e. so then it is 9*4+64. then the m. so then it is 36+64=100

THE ANSWER IS A COINCEDINCE!!!

really it is here is another; 9*4+x^3 and make it 9*4+5^3 the same thing pEmdas so it is 9*4+125

then it is 36+125=161

another is 9*4+6^3 i know, no variable. so it is 36+216=252 see the interval? that is what makes it a quadradic equation, not linear 

now i hope you know more about quadratic equations
