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("PolynomialFactors-Strict"); 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: |
