    Factorise the expressions.

    am2 + bm2 + bn2 + an2

    We can take out m2 as common from the first two terms and n2 as common from the last two terms.

    ∴      am2 + bm2 + bn2 + an2 = m2(a + b) + n2(b + a)

                                             = m2(a + b) + n2 (a + b)

                                              = (a + b)[m2 + n2]
