PG problem file  Explanation 

Problem tagging: 

DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "contextPolynomialFactors.pl", "contextLimitedPowers.pl", ); TEXT(beginproblem()); 
Initialization:
We require additional contexts provided by 
# # Expanded form # Context("Numeric"); $poly = Compute("8x^2+28x+12"); # # Factored form # Context("PolynomialFactorsStrict"); Context()>flags>set(singleFactors=>0); LimitedPowers::OnlyIntegers( minPower => 0, maxPower => 1, message => "either 0 or 1", ); $factored = Compute("4(2x+1)(x+3)"); 
Setup:
For the factored form we need to change to the 
Context()>texStrings; BEGIN_TEXT Write the quadratic expression \( $poly \) in factored form \( k(ax+b)(cx+d) \). $BR $BR \{ ans_rule(30)\} END_TEXT Context()>normalStrings; 
Main Text:
We should explicitly tell students to enter answers in the form 
$showPartialCorrectAnswers = 1; ANS( $factored>cmp() ); 
Answer Evaluation: 
Context()>texStrings; BEGIN_SOLUTION ${PAR}SOLUTION:${PAR} Solution explanation goes here. END_SOLUTION Context()>normalStrings; COMMENT('MathObject version.'); ENDDOCUMENT(); 
Solution:
