Hello,
\n" ); document.write( "Here's the way to solve this.
\n" ); document.write( "X*3+6X*2+5X+30 Let's work on the first two:
\n" ); document.write( "X*3+6X*2 and rewrite this as: x^2(x+6)
\n" ); document.write( "Now let's work on the last two
\n" ); document.write( "5X+30 and rewrite this as: 5(x+6)
\n" ); document.write( "Notice we have in both parenthesis the same (x+6) so now we can rewrite the whole
\n" ); document.write( "polynomial as:
\n" ); document.write( "(x^2+5)(x+6)=0 (I see the original didn't have it equal to zero but should be)
\n" ); document.write( "Now we can solve for x
\n" ); document.write( "x^2+5=0 Subtract 5 from both sides to give us:
\n" ); document.write( "x^2=-5 Sq rooting both sides gives us a negative sq rt so we know that's not right.
\n" ); document.write( "x+6=0 Subtract 6 from both sides gives us:
\n" ); document.write( "x=-6 Plug this into the original equation and it works out.
