Hello!
\n" ); document.write( "In your trinomial
\n" ); document.write( "\"x%5E2-3x+%2B+7\"\r
\n" ); document.write( "\n" ); document.write( "We have that a = 1, b= -3 and c = 7. The ac test consists of checking whether there are two numbers whose produce is equal to a*c and whose sum is equal to be.\r
\n" ); document.write( "\n" ); document.write( "In your case, ac = 1*7 = 7. Since 7 is a prime number, the only pair of numbers whose product is 7 is 1 and 7, or -1 and -7.. In either case, their sum is NOT equal to -3 (1 + 7 = 8 and -1 + (-7) = -8).\r
\n" ); document.write( "\n" ); document.write( "We conclude that this trinomial cannot be factored.\r
