Problem tagging:

DOCUMENT();

loadMacros(
"PGstandard.pl",
"MathObjects.pl",
"AnswerFormatHelp.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.

Context()->texStrings;
BEGIN_TEXT
