You can put this solution on YOUR website!
$\"x%5E2=5x%2B36\"$ Set the problem =0
\n" ); document.write( " $\"x%5E2-5x-36=5x-5x%2B36-36\"$
\n" ); document.write( " $\"x%5E2-5x-36=0\"$ Factor.
\n" ); document.write( "(x___)(x___) Two numbers that multiply to give you -36, but add to give -5 are -9 and +4, -9*4=-36 and -9+4=-5
\n" ); document.write( "(x-9)(x+4)=0 Use the zero product property and set each parenthesis=0
\n" ); document.write( "x-9=0
\n" ); document.write( "x=9
\n" ); document.write( "and
\n" ); document.write( "x+4=0
\n" ); document.write( "x=-4
\n" ); document.write( "x={-4,9}
\n" ); document.write( "Check
\n" ); document.write( " $\"%28-4%29%5E2=5%28-4%29%2B36\"$
\n" ); document.write( " $\"16=-20%2B36\"$
\n" ); document.write( " $\"16=16\"$ -4 checks out.
\n" ); document.write( " $\"%289%29%5E2=5%289%29%2B36\"$
\n" ); document.write( " $\"81=45%2B36\"$
\n" ); document.write( " $\"81=81\"$ 9 checks out also, we're right!!!
\n" ); document.write( "Happy Calculating!!! \n" ); document.write( "
