Find all real solutions of the given equation:
\n" ); document.write( "(x^2 - x)^2 - 63(x^2-x) - 648 = 0
\n" ); document.write( "---
\n" ); document.write( "Let w = x^2-x
\n" ); document.write( "---
\n" ); document.write( "Your problem:
\n" ); document.write( "w^2 - 63w - 648 = 0
\n" ); document.write( "Factor:
\n" ); document.write( "(w+9)(w-72) = 0
\n" ); document.write( "w = -9 or w = 72
\n" ); document.write( "----
\n" ); document.write( "Solve for \"w\":
\n" ); document.write( "If w = -9 you get:
\n" ); document.write( "x^2-x = -9
\n" ); document.write( "x^2-x+9 = 0
\n" ); document.write( "Use the quadratic formula to solve.
\n" ); document.write( "--------------
\n" ); document.write( "If w = 72
\n" ); document.write( "x^2-x 72
\n" ); document.write( "x^2-x-72 = 0
\n" ); document.write( "Factor:
\n" ); document.write( "(x-9)(x+8) - 0
\n" ); document.write( "x = 9 or x = -8
\n" ); document.write( "======================
