GCSE Maths Practice: simplifying-expressions

Question 1 of 10

Factorise the expression completely by taking out the highest common factor (HCF).

›

\( \begin{array}{l}\textbf{Factorise fully:} \\ 15a^5b^3 - 10a^3b^2 + 5a^4b^4\end{array} \)

Choose one option:

Check signs and powers carefully. Divide each term by the HCF to simplify correctly.

When factorising, always look for the largest powers of variables and numerical factors shared by all terms.
