\"x%5E2+=+5x+%2B+2\"
\n" ); document.write( "\"x%5E2-5x+=+cross%285x+-5x%29%2B2\" Get the 5x term to the left side
\n" ); document.write( "\"x%5E2-5x+=+2\"Take half of the 2nd coefficient and square it \"%281%2F2%2A5%29%5E2=25%2F4\"
\n" ); document.write( "\"x%5E2-5x%2B25%2F4+=+2%2B25%2F4\" Add this value to both sides
\n" ); document.write( "General form of perfect square
\n" ); document.write( "\"y=%28x%2B-b%29%5E2%2Bk\" To find value of b, take half of 2nd coefficient.
\n" ); document.write( "\"%28x-5%2F2%29%5E2=8%2F4%2B25%2F4\"
\n" ); document.write( "\"%28x-5%2F2%29%5E2=33%2F4\"
\n" ); document.write( "\"%28x-5%2F2%29%5E2-33%2F4=0\"
\n" ); document.write( "Answer: \"y=%28x-5%2F2%29%5E2-33%2F4\"
\n" ); document.write( "If you graph y=x^2 - 5x - 2 and y=(x-5/2)^2-33/4 together they should be the same graph, verifying the answer
