Algebra.Com's Answer #75126 by JP(22)![]() ![]() You can put this solution on YOUR website! To set this up in base form for quadratic equations it must look like this... \n" ); document.write( "ax^2+bx+c=0 \n" ); document.write( "So, your equation becomes: x^2+8x+16=0 \n" ); document.write( "In factored form it becomes: (x+4)(x+4)=0 \n" ); document.write( "Both solutions will be the same in this case...but this will usually not be the case.\r \n" ); document.write( "\n" ); document.write( "(x+4)=0 \n" ); document.write( "x=-4 or x=-4 \n" ); document.write( "I am a little rusty but I think is is called a \"double root\".\r \n" ); document.write( "\n" ); document.write( "Plug the solution -4 in for every instance of x to prove the solution is valid. \n" ); document.write( "4^2+8(-4)+16=0 \n" ); document.write( "16+-32+16=0 \n" ); document.write( "-16+16=0 \n" ); document.write( "0=0 \n" ); document.write( " |
