Practice problem
When you factor the GCF out of the radical, what does this expression look like?
9x2y4−x2+9xy2+4y49x^2y^4\sqrt{-x^2+9xy^2+4y^4}9x2y4−x2+9xy2+4y4
3xy2−9x4y4+81x3y6+36x2y83xy^2\sqrt{-9x^4y^4+81x^3y^6+36x^2y^8}3xy2−9x4y4+81x3y6+36x2y8
−3xy2x2+9xy2+4y4-3xy^2\sqrt{x^2+9xy^2+4y^4}−3xy2x2+9xy2+4y4
9x2y4−x2+9xy2+4y29x^2y^4\sqrt{-x^2+9xy^2+4y^2}9x2y4−x2+9xy2+4y2
