I am given the equation f(x)=300x-11x squared +2. I am asked to find the maximum. Normally the homework problems show step by step instruction although this one isn't. Can you please help we with this

These sure are some big numbers that don't seem to cancel. Are you sure you submitted the problem correctly?
\n" ); document.write( "\"f%28x%29+=+300x+-+11x%5E2+%2B+2\"_____\"f%28x%29+=+2+%2B+300x+-+11x%5E2\"
\n" ); document.write( "The maximum occurs at the x coordinate of the vertex, or at \"x+=+-+b%2F%282a%29\", or \"x+=+-+300%2F%282+%2A+-+11%29\", or \"x+=+%28-+300%29%2F%28-+22%29\", or \"x+=+150%2F11\"
\n" ); document.write( "\"f%28x%29_or_y+=+2+%2B+300x+-+11x%5E2\"
\n" ); document.write( "\"f%28x%29_or_y+=+2+%2B+300%28150%2F11%29+-+11%28150%2F11%29%5E2\" ----- Substituting \"x+=+150%2F11\", where the maximum occurs
\n" ); document.write( "\"f%28x%29_or_y+=+2+%2B+%2845000%2F11%29+-+11%2822500%2F121%29\"
\n" ); document.write( "\"f%28x%29_or_y+=+2+%2B+%2845000%2F11%29+-+%2822500%2F11%29\"
\n" ); document.write( "\"f%28x%29_or_y+=+%2822%2F11%29+%2B+%2845000%2F11%29+-+%2822500%2F11%29\"
\n" ); document.write( "Maximum occurs at: \"f%28x%29_or_y+=+22522%2F11\", or \"highlight_green%28y+=+2047.454545%29\" ≈ 2047.45
\n" ); document.write( "You can do the check!!
