Answer:
ASA: If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent. SAS: If any two angles and the included side are the same in both triangles, then the triangles are congruent.
A and E
Just rearrange where the -5 is
(x+2y+z) (x-2y-z)
= x^2 - 2xy - xz + 2xy - 4y^2 - 2yz + xz - 2yz - z^2 = x^2 - 4y^2 - 4yz -z^2
Hope it helped!
