Algebra.Com's Answer #64657 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! solve the following equation by using the square root method? 9x^2-30x+25=-1 \n" ); document.write( "---------- \n" ); document.write( "(3x-5)^2 = -1 \n" ); document.write( "(3x-5)^2+1 = 0 \n" ); document.write( "Factor to get: \n" ); document.write( "(3x-5-i)(3x-5+i) = 0 \n" ); document.write( "3x-5-i = 0 or 3x-5+i = 0 \n" ); document.write( "x=(5+i)/3 or x=(5-i)/3 \n" ); document.write( "================ \n" ); document.write( "Here's the square root method. \n" ); document.write( "(3x-5)^2 = -1 \n" ); document.write( "Take the square root of both sides to get: \n" ); document.write( "3x-5 = i or 3x-5 = -i \n" ); document.write( "3x=5+i or 3x = 5-i \n" ); document.write( "x = (5+i)/3 or x = (5-i)/3 \n" ); document.write( "==================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
