Answer:


\sf 4x^2-20x+25

Explanation:


\sf (2x - 5)^2

We can written it as:


\sf (2x - 5)(2x - 5)


\sf 2x(2x - 5) - 5(2x - 5)

Opening Bracket


\sf (2x * 2x) + (2x * -5) + (-5 * 2x) + (-5 * -5)


\sf 4x^2 + (-10x - 10x) + 25


\sf 4x^2 - 20x + 25

Therefore, Trinomial of
\sf (2x - 5)^2 \:is\: 4x^2 - 20x + 25.
