Find the polynomial with the lowest degree having the following zeros -2, 2-i \n" ); document.write( "-------- \n" ); document.write( "Complex roots always occur in pairs, so add 2+i as a zero \n" ); document.write( "--> (x+2)*(x-2-i)*(x-2+i) \n" ); document.write( "= \n" ); document.write( "= \n" ); document.write( "--------------- \n" ); document.write( "A)x^3+6x^2+10 \n" ); document.write( "B)6x^2+13x+10 \n" ); document.write( "C)x^3+6x^2+13x+10 \n" ); document.write( "D)x^3+2x+3x-10 \n" ); document.write( "E)None of the above \n" ); document.write( " |
