Hello,
\n" ); document.write( "I assume you want to solve this. (x-5)^2-x=30
\n" ); document.write( "Let's expand this out to:
\n" ); document.write( "x^2-10x+25-x=30 Combine terms and subtract 30 from both sides to get:
\n" ); document.write( "x^2-11x-5=0
\n" ); document.write( "We'll need the quadratic formula to solve this:
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$ Entering the values looks like this:
\n" ); document.write( "{x = (+11 +- sqrt( 121+20 ))/(2) This comes out to be
\n" ); document.write( "x=11.44 and
\n" ); document.write( "x=-.437 These are rounded off.
\n" ); document.write( "Plug these answers into the original to see if they work.
