Answer 2

hint:
a perfect square trinomial, is a trinomial of this type:
\[\huge {k^2}{x^2} + 2khx + {h^2}\]

Answer 3

for example the third option can not be such trinomial, since \(10\) is not a perfect square

Answer 4

that's right! We can write this:
\[\huge {\left( {4x - 1} \right)^2} = 16{x^2} + 1 - 8x\]
