Algebra.Com's Answer #393622 by Theo(13342)![]() ![]() You can put this solution on YOUR website! start with: \n" ); document.write( "sqrt(5x+5) = x+1 \n" ); document.write( "square both sides of this equation to get: \n" ); document.write( "5x+5 = (x+1)^2 \n" ); document.write( "simplify to get: \n" ); document.write( "5x+5 = x^2+2x+1 \n" ); document.write( "subtract 5x and subtract 5 from both sides of the equation to get: \n" ); document.write( "0 = x^2-3x-4 \n" ); document.write( "this is the same as: \n" ); document.write( "x^2-3x-4 = 0 \n" ); document.write( "factor this quadratic equation to get: \n" ); document.write( "(x-4)*(x+1) = 0 \n" ); document.write( "solve for x to get: \n" ); document.write( "x=4, x=-1 \n" ); document.write( "both of these solutions are good as you will see when you substitute for x in the original equation using each in turn. \n" ); document.write( " \n" ); document.write( " |
