Algebra.Com's Answer #30820 by jcmtnez(53)![]() ![]() ![]() You can put this solution on YOUR website! That polynomial can be expressed as:\r \n" ); document.write( "\n" ); document.write( "(x-1)(x-1)(x-3) Now we have to expand this expression\r \n" ); document.write( "\n" ); document.write( "(x-1)(x-1)(x-3)=(x^2-2x+1)(x-3)=x^3-2x^2+x-3x^2+6x-3=x^3-5x^2+7x-3\r \n" ); document.write( "\n" ); document.write( "So the polynomial of degree three that have the solution (1,1,3) is \n" ); document.write( "x^3-5x^2+7x-3\r \n" ); document.write( "\n" ); document.write( "I'm glad to help you anytime \n" ); document.write( " |
