Algebra.Com's Answer #668033 by stanbon(75887) ![]() You can put this solution on YOUR website! I need help finding the polynomial with the given zeros of 0, 8, and 1+sqrt2i with real coefficients please! I've tried and so far all I've gotten is x^2-8x-x+sqrt2i+8+sqrt2i \n" ); document.write( "---- \n" ); document.write( "If the coefficients are to be Real, 1-sqrt(2)i must also be a zero \n" ); document.write( "------ \n" ); document.write( "Zeroes:: 0, 8, 1+sqrt(2)i, 1-sqrt(2)i \n" ); document.write( "------------ \n" ); document.write( "f(x) = x(x-8)(x-(1+sqrt(2)i)(x-(1-sqrt(2)i) \n" ); document.write( "---- \n" ); document.write( "f(x) = x(x-8)((x-1)-sqrt(2)i)((x-1)+sqrt(2)i) \n" ); document.write( "----- \n" ); document.write( "f(x) = x(x-8)((x-1)^2 +2) \n" ); document.write( "--- \n" ); document.write( "f(x) = x(x-8)(x^2 -2x + 3) \n" ); document.write( "------------------------------ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
