You can put this solution on YOUR website!
I'm assuming that expression equates to zero.
\n" ); document.write( ":
\n" ); document.write( "5t(t+5)+(t-1)(t+6)= 0
\n" ); document.write( ":
\n" ); document.write( "5(t^2) + 25t + (t-1)(t+6)= 0
\n" ); document.write( ":
\n" ); document.write( ":Expand the back part of the equation
\n" ); document.write( ":
\n" ); document.write( "5(t^2) + 25t + (t^2) + 5t - 6 = 0
\n" ); document.write( ":
\n" ); document.write( "6(t^2) + 30t - 6 = 0
\n" ); document.write( ":
\n" ); document.write( "(t^2) + 5t - 1 = 0
\n" ); document.write( ":
\n" ); document.write( "Using formula:
