How would I Factor this equation,if f(t)=2t^2-4t-1,find- with f(2) and f(1).
\n" ); document.write( "Do, I replace (t), with 2 and 1 in the equation.
\n" ); document.write( "-----------------
\n" ); document.write( "2t^2-4t-1
\n" ); document.write( "Use the quadratic formula:
\n" ); document.write( "t = [4 +- sqrt(16 - 4*2*-1)]/4\r
\n" ); document.write( "\n" ); document.write( "t =[4 +- sqrt(24)]/4\r
\n" ); document.write( "\n" ); document.write( "t =[4 +- 2sqrt(6)]/4\r
\n" ); document.write( "\n" ); document.write( "t = 1 + (1/2)sqrt6 or t = 1 - (1/2)sqrt6\r
\n" ); document.write( "\n" ); document.write( "Factors:
\n" ); document.write( "(t-1-(1/2)sqrt6)(t-1+(1/2)sqrt6)
\n" ); document.write( "---------------
\n" ); document.write( "f(t)=2t^2-4t-1,find- with f(2) and f(1).
\n" ); document.write( "Do, I replace (t), with 2 and 1 in the equation.
\n" ); document.write( "Yes, that is what you do.\r
\n" ); document.write( "
