Find the center of the ellipse 16x^2 + 25y^2 + 32x - 150y = 159
\n" ); document.write( "---------------
\n" ); document.write( "Complete the square on the x-terms and the y-terms separately:
\n" ); document.write( "---
\n" ); document.write( "16(x^2 + 2x + ?) + 25(y^2-6y+?) = 159 + ? + ?
\n" ); document.write( "16(x^2 + 2x + 1) + 25(y^2 -6y + 9) = 159 +16*1 + 25*9
\n" ); document.write( "---
\n" ); document.write( "16(x+1)^2 + 25(y-3)^2 = 400
\n" ); document.write( "----------------------
\n" ); document.write( "Center: (-1,3)
