$\"4r%5E2\"$ +3r-10
\n" ); document.write( "First of all you kno you are going to have a + and a - in the parenthesis;
\n" ); document.write( "(_ + _ )(_ - _)
\n" ); document.write( "Now you need to list your factors of 4;
\n" ); document.write( "1,4; 2;2
\n" ); document.write( "List factors of 10;
\n" ); document.write( "10,1; 2;5
\n" ); document.write( "Now you need to figure out which of these work; to do that;
\n" ); document.write( "lwts look at 1,4 and 2,5;
\n" ); document.write( "we multiply; 1*2 and 4*5; then add the answers;
\n" ); document.write( "2-20=-18 so we know that is wrong;
\n" ); document.write( "lets look at;
\n" ); document.write( "1*5=5
\n" ); document.write( "4*2=8, this may work;
\n" ); document.write( "Now by looking at the original trinomial e know the larger number is going to be +, because there is a +3;
\n" ); document.write( "(r+2)(4r-5)
\n" ); document.write( "I know this is hard to understand just by trying to read my explanation. I hope this helps some. If you have more questions e-mail me.
\n" ); document.write( "=) \n" ); document.write( "
