Algebra.Com's Answer #631897 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Find all solutions of the equation x^2+4x+10=0 by completing the square. Express the soutions in the form a+bi: \n" ); document.write( "First input the solution with b<0 here: \n" ); document.write( "the real number a equals \n" ); document.write( "and the real number b equals \n" ); document.write( "Then input the solution with b>0 here: \n" ); document.write( "the real number a equals:: 1 \n" ); document.write( "and the real number b equals:: 4 \n" ); document.write( "---- \n" ); document.write( "x^2+4x+10 = 0 \n" ); document.write( "---- \n" ); document.write( "x^2+4x + 4 = -6 \n" ); document.write( "---- \n" ); document.write( "(x+2)^2 = -6 \n" ); document.write( "------ \n" ); document.write( "x+2 = sqrt(6)i or x+2 = -sqrt(6)i \n" ); document.write( "------------------------- \n" ); document.write( "Ans: x = -2 + i*sqrt(6) or x = -2 - isqrt(6) \n" ); document.write( "-------------------------------------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "---------------- \n" ); document.write( " |
