The problem is written as √7x+36=x+4. With the bar from the square root sign extending over the 7x+36
\n" ); document.write( "----
\n" ); document.write( "sqrt(7x+36) = x+4
\n" ); document.write( "---
\n" ); document.write( "Square both sides to get:
\n" ); document.write( "7x+36 = x^2+8x+16
\n" ); document.write( "---
\n" ); document.write( "x^ + x -20 = 0
\n" ); document.write( "---
\n" ); document.write( "Factor:
\n" ); document.write( "(x+5)(x-4) = 0
\n" ); document.write( "---
\n" ); document.write( "x = -5 or x = 4
\n" ); document.write( "---
\n" ); document.write( "Check the \"answers\" in the original problem:
\n" ); document.write( "sqrt(7x+36) = x+4
\n" ); document.write( "x = -5 ?
\n" ); document.write( "sqrt(-35+36) = -5+4
\n" ); document.write( "sqrt(1) = -1
\n" ); document.write( "No
\n" ); document.write( "----
\n" ); document.write( "x = 4?
\n" ); document.write( "sqrt(28+36) = 4+4
\n" ); document.write( "sqrt(64) = 8
\n" ); document.write( "Yes
\n" ); document.write( "-------------------
\n" ); document.write( "Final Answer: x = 4
\n" ); document.write( "=============================
