Algebra.Com's Answer #672741 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! x^2-18x+81 =17+81. Take half the middle term and square it. This will be (x-9)^2=98, x-9=sqrt(98)=7 sqrt (2), and x=9+/-7 sqrt (2). \n" ); document.write( "------------------------- \n" ); document.write( "4x^3-20x^2+24x=0 \n" ); document.write( "factor out a 4x \n" ); document.write( "4x(x^2-5x+6)=0 \n" ); document.write( "4x(x-2)(x-3)=0 \n" ); document.write( "roots are 0,2,3 \n" ); document.write( " \n" ); document.write( "----------------------- \n" ); document.write( "x^6(6x-11)(7x-8)=0 \n" ); document.write( "Set the factors equal to 0 and solve for x, which will be 0, 11/6, and 8/7. \n" ); document.write( "-------------------------- \n" ); document.write( "6x^2-42x-54 \n" ); document.write( "6(x^2-7x-9) \n" ); document.write( "----------------------- \n" ); document.write( "x^2-9x+3=0 \n" ); document.write( "x=(1/2)(9 +/-sqrt(81-12))=(1/2)(9+sqrt(69)) and (1/2)(9-sqrt (69)) \n" ); document.write( "--------------- \n" ); document.write( "x^2=-20 \n" ); document.write( "x=+/-sqrt(-4)*sqrt(5) \n" ); document.write( "+/- 2i sqrt (5) \n" ); document.write( " |
