You can put this solution on YOUR website!
can you u show me how to put a equation in vertex form?
\n" ); document.write( "---
\n" ); document.write( "You need to \"complete the square\".
\n" ); document.write( "---
\n" ); document.write( "Example:
\n" ); document.write( "y = 2x^2 + 3x + 5
\n" ); document.write( "----
\n" ); document.write( "y = 2(x^2 + (3/2)x) + 5
\n" ); document.write( "---
\n" ); document.write( "y = 2(x^2+(3/2)x+(3/4)^2) + 5 - (3/4)^2
\n" ); document.write( "--
\n" ); document.write( "y = 2(x+(3/4))^2 + (80/16)-(9/16)
\n" ); document.write( "---
\n" ); document.write( "y = 2(x+(3/4)^2 + (71/16)
\n" ); document.write( "----
\n" ); document.write( "Vertex: (-3/4,71/16)
