Algebra.Com's Answer #485195 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! Solve the equation: 49y - 21sqrt(y) + 2=0\r \n" ); document.write( "\n" ); document.write( "I have tried squaring the equation to remove the √ but I don't think this is right. \n" ); document.write( "Sub x for sqrt(y) \n" ); document.write( "--> 49x^2 - 21x + 2 = 0 \n" ); document.write( "(7x - 1)*(7x - 2) = 0 \n" ); document.write( "Then sub back, and square to get y. \n" ); document.write( " |
