Give exact and approximate solutions to three decimal places:
\n" ); document.write( "y^2-2y+1=100.
\n" ); document.write( "***
\n" ); document.write( "To find the zeros you can either factor or use the quadradic formula.
\n" ); document.write( "Factoring: set expression = zero, use trial and error method, then check using FOIL.
\n" ); document.write( "y^2-2y-99=0
\n" ); document.write( "..
\n" ); document.write( "Quadratic formula: \"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\" For given equation, a=1, b=-2, and c=-99
\n" ); document.write( "ans:
\n" ); document.write( "y=-9 or 11
\n" ); document.write( "
\n" );
