Write the equation of the circle with centre (12,−3)\left(\dfrac12,-3\right) and radius 55 in general form. (a) x2+y2+x+6y−634=0x^{2}+y^{2}+x+6y-\dfrac{63}{4}=0 (b) x2+y2−x+6y−634=0x^{2}+y^{2}-x+6y-\dfrac{63}{4}=0 (c) x2+y2−x+6y+634=0x^{2}+y^{2}-x+6y+\dfrac{63}{4}=0 (d) x2+y2−2x+6y−15=0x^{2}+y^{2}-2x+6y-15=0
