Let’s resolve into factors:99a2-202ab + 99b2

99a2-202ab + 99b2=99a2-121ab-81ab + 99b2=11a(9a-11b)-9b(9a-11b)=(11a-9b)(9a-11b)∴the factors of 99a2-202ab + 99b2 are (11a-9b)(9a-11b)

Let’s resolve into factors:
99a²-202ab + 99b²

99a²-202ab + 99b²

=99a²-121ab-81ab + 99b²

=11a(9a-11b)-9b(9a-11b)

=(11a-9b)(9a-11b)

∴the factors of 99a²-202ab + 99b² are (11a-9b)(9a-11b)
