Which method should be used (factoring, square root property, completing the square, and the quadratic formula)
\n" ); document.write( "to solve each of the following quadratic equations. Each method can be used only ONCE and why that method?
\n" ); document.write( "
\n" ); document.write( " A) 4x^2 – 27 = 0
\n" ); document.write( " B) 4x^2 – 8x – 5 = 0
\n" ); document.write( " C) 4x^2 – 8x – 12 = 0
\n" ); document.write( " D) 4x^2 – 9x – 7 = 0
\n" ); document.write( "

Easiest methods:
\n" );
document.write( "A) 4x^2 – 27 = 0 <======== Square-root property
\n" );
document.write( "B) 4x^2 – 8x – 5 = 0 <==== FACTORING, as this TRINOMIAL CAN be factored
\n" );
document.write( "C) 4x^2 – 8x – 12 = 0 <=== Factor out GCF, 4, and then use FACTORING, as the resulting TRINOMIAL can be factored
\n" );
document.write( "D) 4x^2 – 9x – 7 = 0 <==== Can't be factored so complete the square, or use the quadratic formula
\n" );
document.write( "Since each method can only be used once, then I'd factor out GCF, 4 and then complete the square for C), 
\n" );
document.write( "and I'd use the quadratic equation formula for D), or vice-versa. So, there you have it. \n" );
document.write( "

\n" );
