Need ! discuss how to convert the standard form of the equation of a circle to the general form. 50 points

Factor -8x3-2x2-12x-3 by grouping what is the resulting expression?

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]
