This is real confusing.. me! in advance : )

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

Factor the polynomial 4x4 – 20x2 – 3x2 + 15 by grouping. what is the resulting expression? (4x2 + 3)(x2 – 5) (4x2 – 3)(x2 – 5) (4x2 – 5)(x2 + 3) (4x2 + 5)(x2 – 3)
