\n" ); document.write( "Solving
\n" ); document.write( " x^2 - 3x - 4 = 0 OR y = (x-3/2)^2 - 25/4 (vertex form by completing square)
\n" ); document.write( "factoring
\n" ); document.write( "(x-4)(x+1)=0 Note:SUM of the inner product(-4x) and the outer product(1*x) = -3x
\n" ); document.write( "(x-4)=0 x = 4
\n" ); document.write( "(x+1)=0 x = -1
\n" ); document.write( "
