Algebra.Com's Answer #165260 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! solve the equation: \n" ); document.write( "square root of(5-x)=x-3 \n" ); document.write( "------------------------------ \n" ); document.write( "sqrt(5-x) = x-3 \n" ); document.write( "Square both sides to get: \n" ); document.write( "5-x = x^2-6x+9 \n" ); document.write( "x^2-5x+4 = 0 \n" ); document.write( "Factor: \n" ); document.write( "(x-4)(x-1) = 0 \n" ); document.write( "x = 4 or x = 1 \n" ); document.write( "--------------------- \n" ); document.write( "Check in the original equation: \n" ); document.write( "If x=4 you get: sqrt(1) = 4-3 which is correct. \n" ); document.write( "------- \n" ); document.write( "If x=1 you get sqrt(4) = 1-3 which is not correct. \n" ); document.write( "----------- \n" ); document.write( "Solution: x = 4 \n" ); document.write( "======================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
