Explain in your own words how to reverse FOIL when factoring a polynomial of the form ax^2 + bx + c when a = 1. Give an example with your explanation.please help,
\n" ); document.write( "-----------------
\n" ); document.write( "Example:
\n" ); document.write( "x^2 + 5x + 6
\n" ); document.write( "Think of two numbers whose product is 6 and whose sum is 5
\n" ); document.write( "The numbers are 3 and 2
\n" ); document.write( "---------------------------
\n" ); document.write( "Rewrite the equation replacing 5x by 3x+2x to get:
\n" ); document.write( "x^2 + 3x + 2x + 6
\n" ); document.write( "----------
\n" ); document.write( "Factor the 1st two and the last two terms separately to get:
\n" ); document.write( "x(x+3)+ 2(x+3)
\n" ); document.write( "Factor again to get:
\n" ); document.write( "(x+3)(x+2)
\n" ); document.write( "-----------------
\n" ); document.write( "That is an example of \"inverse FOIL\"; it is also sometimes
\n" ); document.write( "called \"the AC Method of factoring\".\r
