How do you solve y=-(x-1)^2-1
\n" ); document.write( "y = 0, FOIL (x-1)(x-1)
\n" ); document.write( "-(x^2 - 2x + 1) - 1 = 0
\n" ); document.write( "the neg changes the signs inside the brackets
\n" ); document.write( "-x^2 + 2x - 1 - 1 = 0
\n" ); document.write( "-x^2 + 2x - 2 = 0
\n" ); document.write( "This equation has no real root, check this using the discriminant b^2 - 4ac
\n" ); document.write( "2^2 - 4(-1*-2) = -8
\n" ); document.write( ":\r
