You can put this solution on YOUR website!
k(4k^2-13k-12) Pull out what they have in common, in this case a k
\n" ); document.write( "Multiply your first value (4) and last value (-12). Find a number that multiplies to get -48 and their sum comes to -13 (which is your middle term).
\n" ); document.write( "3(-16) works for both situations.\r
\n" ); document.write( "\n" ); document.write( "k[4k^2-16k+3k-12] Replaced middle term with the values you found. Order doesn't matter.
\n" ); document.write( "k[4k(k-4)+3(k-4)] Split the 4 terms into two sets and pull out what the pairs have in common. Your two parenthesis inside should always match if you did this right.\r
\n" ); document.write( "\n" ); document.write( "k(k-4)(4k+3) Write the repeated set once and the other set comes from the values that you factored out. Don't forget the k from the beginning that was pulled out. It is still out there.\r
\n" ); document.write( "\n" ); document.write( "Hard to follow this one. A little complicated. Hope you could stay with me. lol. Good luck.
