You can put this solution on YOUR website!
1: For what real number k, does 3x^2 – k factor as 3(x – 2)(x + 2)?
\n" ); document.write( "If 3x^2-k = 3(x-2)(x+2)
\n" ); document.write( "then 3x^2-k = 3(x^2-4)
\n" ); document.write( "and 3x^2-k = 3x^2-12
\n" ); document.write( "Therefore k would have to equal 12
\n" ); document.write( "-------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "2: Which of the following products is not equivalent to the others? Explain your answer.
\n" ); document.write( "1. (2x – 4)(x + 3)= 2x^2+2x-12
\n" ); document.write( "2. 2(x – 2)(x + 3)= 2(x^2+x-6)=2x^2+2x-12
\n" ); document.write( "3. (x – 2)(2x + 6)= 2x^2+2x-12
\n" ); document.write( "4. (2x – 4)(2x + 6)= 4x^2+4x-24
\n" ); document.write( "Ans: #4 is double each of the others
