How would you put these in standard form (AX+BX=C):
X sguared+ Ysquared -12X+ 14Y +9=0
Ysquared -8X +10Y -7=0
Also what would be the sum of:
729/1024+243/512+81/256+...+4/729

Complete the square, then check to see if it's an ellipse or hyperbola. Set equal to one. Make sure there is a denominator for each term.

1 RespuestaYou sure it's not AX^2+BX=C?
