If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
x2+y2−3x−y=0
Simplify
x2+y2−y−3x=0
Rewrite in standard form
x2−3x+y2−y=0
Substitute a=1,b=−3 and c=y2−y into the quadratic formula x=2a−b±b2−4ac
x=23±(−3)2−4(y2−y)
Simplify the expression
