Find the zeroes of ax^2+bx = y-c
\n" ); document.write( "By completing the square
\n" ); document.write( "---
\n" ); document.write( "y = ax^2 + bx + c = 0
\n" ); document.write( "Divide by a
\n" ); document.write( "x^2 + (b/a)x + c/a = 0
\n" ); document.write( "x^2 + (b/a)x = -c/a
\n" ); document.write( "Make left side a square by adding (b/2a)^2
\n" ); document.write( "x^2 + (b/a)x + b^2/4a^2 = -c/a + b^2/4a^2
\n" ); document.write( " $\"%28x+%2B+b%2F2a%29%5E2+=+b%5E2%2F4a%5E2+-+4ac%2F4a%5E2\"$
