Hello,
\n" ); document.write( "The way to factor this is look at the first two terms 2x^3+10x. This can be rewritten as:
\n" ); document.write( "2x^2(x+5)
\n" ); document.write( "Now let's look at the last two terms. x+5 or 1(x+5) Notice it matches the above in parenthesis. This can be rewritten as:
\n" ); document.write( "(2x^2+1)(x+5) Now we can solve for x
\n" ); document.write( "x=-5
\n" ); document.write( "2x^2+1 = 0 Rewritten
\n" ); document.write( "2x^2=-1
\n" ); document.write( "x^2=-1/2
\n" ); document.write( "x=square root of -1/2
\n" ); document.write( "Make sense?
