sqrt(2x+3)-sqrt(x+7)=1
\n" ); document.write( "Square both sides to get:
\n" ); document.write( "(2x+3) - 2sqrt[(2x+3)(x+7)] +(x+7) = 1
\n" ); document.write( "----------
\n" ); document.write( "Simplify:
\n" ); document.write( "(3x+10) - 2sqrt[.....] = 1
\n" ); document.write( "-------------
\n" ); document.write( "Isolate the sqrt term:
\n" ); document.write( "-2sqrt[.....} = 1-3x-10
\n" ); document.write( "------------
\n" ); document.write( "Simplify:
\n" ); document.write( "-2sqrt[..........] = -(3x+9)
\n" ); document.write( "-------------------
\n" ); document.write( "Square both sides to get:
\n" ); document.write( "4(2x+3)(x+7) = 9x^2+54x+81
\n" ); document.write( "4(2x^2+17x+21) = 9x^2+54x+81
\n" ); document.write( "8x^2+68x+84 = 9x^2+54x+81
\n" ); document.write( "x^2-14x-3=0
\n" ); document.write( "-------------
\n" ); document.write( "Use the quadratic formula:
\n" ); document.write( "x = [14+-sqrt(14^2-4*-3)]/2
\n" ); document.write( "x = [14 +- 14.42]/2
\n" ); document.write( "x = 14.21... or x = -0.2111...
\n" ); document.write( "----------------
\n" ); document.write( "These answers need to be checked in the original equation as
\n" ); document.write( "one or both may be extraneous.
