Acircle has a diameter will endpoints of (-2,8) and (6, 4). what is the center of the circle

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.

Factor 15x^3 - 5x^2 +6x-2 by grouping. what is the resulting expression
