Please help me with this.I'm not sure how to do this.I have to solve these by factoring:
\n" ); document.write( "I have to factor
\n" ); document.write( "a. x^2 +14x + 49 = 0
\n" ); document.write( "b. x^2 - 16 = 0
\n" ); document.write( "**
\n" ); document.write( "a. x^2 +14x + 49 = 0
\n" ); document.write( "This equation is a perfect square
\n" ); document.write( "(x+7)^2=0
\n" ); document.write( "x=-7 (mult. 2)
\n" ); document.write( "..
\n" ); document.write( "b. x^2 - 16 = 0
\n" ); document.write( "This equation is a difference of 2 squares
\n" ); document.write( "(x+4)(x-4)=0
\n" ); document.write( "x=-4
\n" ); document.write( "or
\n" ); document.write( "x=4
\n" ); document.write( "
\n" );
