Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.

Segment xy is dilated through point m with a scale factor of 2. which segment shows the correct result of the dilation
