👉 A quadrinomial is a type of polynomial that can be defined by an expression containing three terms. These are also known as perfect squares, and they have a special form in algebraic manipulation. For example: - \( x^2 + 3x + 1 \) is a perfect square. - \( y^2 - 4y + 4 \) is another perfect square. - \( z^2 - 6z + 9 \) is also a perfect square
