Question

find the product
(x+8)^2
(a-4)^2
(2f-1)^2
(5p+)^2
(-7t+4)^2
(-12-n)^2
(2a+b)^2
(6x-3y)^2

Answer 1

I'll expand each squared binomial using (u+v)^2 = u^2 + 2uv + v^2. One entry is incomplete — please confirm the missing term in "(5p+)^2".

Expanded:

1) (x+8)^2 = x^2 + 16x + 64
2) (a-4)^2 = a^2 - 8a + 16
3) (2f-1)^2 = 4f^2 - 4f + 1
4) (5p+)^2 — incomplete; please tell me what follows the + so I can expand it
5) (-7t+4)^2 = 49t^2 - 56t + 16
6) (-12-n)^2 = (n+12)^2 = n^2 + 24n + 144
7) (2a+b)^2 = 4a^2 + 4ab + b^2
8) (6x-3y)^2 = 36x^2 - 36xy + 9y^2

Tell me the missing term in (5p+) and I will expand that one too.
