GCSE Maths Practice: simplifying-expressions

Question 10 of 10

Recognise perfect square trinomials and expand them.

‹

\( \begin{array}{l}\textbf{Which is equivalent to }(x - 2)^2\textbf{?}\end{array} \)

Choose one option:

\( x^2 - 4x + 4 \) \( x^2 - 2 \) \( x^2 + 4x + 4 \) \( x^2 - 2x + 4 \)

Always expand carefully and combine like terms to simplify correctly.

The square of a difference formula: (a-b)^2 = a^2 - 2ab + b^2. Apply it to x-2.
