How do you solve this equation using the quadratic formula?
\n" ); document.write( "4(x-2)^2=20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First expand the above and rewrite in the standard form ax^2 + bx + c = 0:\r
\n" ); document.write( "\n" ); document.write( "4(x-2)^2 = 20
\n" ); document.write( "4 = 20
\n" ); document.write( "4x^2 - 16x + 16 = 20
\n" ); document.write( "4x^2 - 16x - 4 = 0\r
\n" ); document.write( "\n" ); document.write( "Here we see a=4, b=-16 and c=-4. Now you can solve using the quadratic formula.
