The release tests for the project says I'm failing toStringPositive. I'm having trouble figuring out what exactly is wrong with my code. Any help is appreciated.</p> <p>I have to create a string representing the Polynomial ax^2+bx+c. These are the <strong>specifications</strong>:</p> <ul> <li>There are never any spaces in the string.</li> <li>Do not include an "*" in the "x^2" and "x" terms. (i.e., create "23x^2", not "23*x^2"). If there are negative terms, they should be represented by subtraction, not addition of a negative term (i.e., create "2x^2+4x-6", not "2x^2+4x+-6".</li> <li>If there are any terms with a 0 coefficient, then skip that term (i.e., create "2x^2-6", not "2x^2+0x-6").</li> <li>If all 3 coefficients are 0, then the string should be "0" If there are any terms with a 1 coefficient, then display that coefficient (i.e., create "2x^2+1x+3", not "2x^2+x+3").</li> <li>If the decimal component of a coefficient is 0, then do not include a decimal portion for that coefficient (i.e., create "23x", not "23.0x"). Note that the MyDouble.toString() method does this for you automatically.</li> </ul>
