DOCUMENT();

loadMacros('PGstandard.pl','MathObjects.pl','PGML.pl','PGcourse.pl');

TEXT(beginproblem());

Initialization: 

Context('Numeric');

$a = non_zero_random(-9,9,1);
do { $b = random(2,9,1); } until ( $b != $a );

$answer1 = Compute("$a");
$answer2 = Compute("$a x^($b) + $b")->reduce();

Setup: We use do { $b = random(2,9,1); } until ( $b != $a ); to generate distinct random numbers. 

BEGIN_PGML
Enter [`[$answer1]`]: [____]{$answer1} [@ helpLink('number') @]*

Enter [`[$answer2]`]: [____]{$answer2} [@ helpLink('formula') @]*
