Use the ac test to determine if the following trinomial can be factored. If it can be factored, find the values of m and n. 3x^2+11x-4
\n" ); document.write( "-----------
\n" ); document.write( "AC = 3*-4 = -12
\n" ); document.write( "b = 11
\n" ); document.write( "--------------
\n" ); document.write( "Think of two numbers whose product is -12 and whose sum is 11
\n" ); document.write( "---------------
\n" ); document.write( "The numbers are -12 and +1
\n" ); document.write( "-----------------
\n" ); document.write( "Rewrite the problem, as follows: 3x^2+12x-x-4
\n" ); document.write( "Factor the 1st two and the last two terms separaely:
\n" ); document.write( "3x(x+4)-(x+4)
\n" ); document.write( "Factor again:
\n" ); document.write( "(x+4)(3x-1)
\n" ); document.write( "====================
