You can put this solution on YOUR website!
That is the property when something times zero will always equal zero.
\n" ); document.write( "Ex.) x^2 + 2x + 1 = 0
\n" ); document.write( "(x + 1)(x + 1) = 0
\n" ); document.write( "(x + 1) must be equal to zero *since they are the same, only one needs to equal zero
\n" ); document.write( "x + 1 = 0
\n" ); document.write( "x = -1 is your answer
\n" ); document.write( "Ex.) x^2 + 5x + 4 = 0
\n" ); document.write( "(x + 4)(x + 1) = 0
\n" ); document.write( "(x + 4) must equal zero
\n" ); document.write( "x + 4 = 0
\n" ); document.write( "x = -4 is one of your answers
\n" ); document.write( "(x + 1) must equal zero
\n" ); document.write( "x + 1 = 0
\n" ); document.write( "x = -1 is your second answer \n" ); document.write( "
