==============================

[tex] \large \bold{\blue{PROBLEM:}} [/tex] Determine the middle term of the following trinomials to make it a perfect square.

  • [tex] 1a^2 - \_\_\_ + 251n^2 [/tex]

[tex] \large \bold{\blue{SOLUTION:}} [/tex] To determine the middle term, refer s, t, and u as the first, middle, and last term in PST respectively. "Twice the product of roots of the first and last term is the middle term"

  • [tex] t = 2\sqrt{s}\sqrt{u} [/tex]

  • [tex] t = 2\sqrt{1}\sqrt{25n^2} [/tex]

  • [tex] t = 2(1)(5n) [/tex]

  • [tex] t = 10n [/tex]

[tex] \large \therefore \underline{\boxed{\tt 1 - \underline{\,\purple{10n}\,} + 25n^2 }} [/tex]
