You can put this solution on YOUR website!
Well, you first have to simplify the $\"%28x-2%29%5E2\"$
\n" ); document.write( "To do that, you can either use FOIL or $\"a%5E2%2B2ab%2Bb%5E2\"$
\n" ); document.write( "I personally like to use the formula because it is much faster.
\n" ); document.write( "After simplifying you should get:
\n" ); document.write( " $\"x%5E2-4x%2B4%2Bx%5E2=10\"$
\n" ); document.write( "Add like terms
\n" ); document.write( " $\"2x%5E2-4x%2B4=10\"$
\n" ); document.write( " $\"2x%5E2-4x-6=0\"$
\n" ); document.write( "To solve
\n" ); document.write( "I would simplify it first
\n" ); document.write( " $\"x%5E2-2x-3=0\"$
\n" ); document.write( "You can factor or use the quadratic formula $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( "I will factor because it is faster.
\n" ); document.write( " $\"%28x-3%29%28x%2B1%29=0\"$
\n" ); document.write( "X=3 or -1
\n" ); document.write( "Hope this helps! \n" ); document.write( "
