I'm trying to factor this polynomial using the ac method:
\n" ); document.write( "6x^2-35x-5
\n" ); document.write( "----
\n" ); document.write( "Comment: There are no 2 numbers whose product is -30 and whose sum is -35.
\n" ); document.write( "So you cannot use the ac method.
\n" ); document.write( "---
\n" ); document.write( "Use the Quadratic formula:
\n" ); document.write( "x = [35 +- sqrt(35^2 - 4*6*-5)]/(2*6)
\n" ); document.write( "----
\n" ); document.write( "x = [35 +- sqrt(1345)]/12
\n" ); document.write( "---
\n" ); document.write( "x = [35 +- 36.67]/12
\n" ); document.write( "----
\n" ); document.write( "x = 5.97 or x = -0.14
\n" ); document.write( "===========================
\n" ); document.write( "Factors would be (x-5.97)(x+0.14)
\n" ); document.write( "Cheers,
