Algebra.Com's Answer #92299 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! x^2-x+1/4\r \n" ); document.write( "\n" ); document.write( "= (x-(1/2))^2 \n" ); document.write( "-------------------- \n" ); document.write( "You recognize that x^2 and (1/4) are both perfect squares. \n" ); document.write( "Then you regognize that 1 is twice the square root of (1/4) \n" ); document.write( "Therefore the trinomial is a perfect square trinomial \n" ); document.write( "and factors as (a-b)^2 \n" ); document.write( "Your a is \"x\"; Your b is \"1/2\" \n" ); document.write( "=============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
