Question statement

For each expression below, collect like terms and expand brackets.

The * symbol is required between algebraic symbols, e.g. $5ab^2$ should be written 5*a*b^2.

Give any introductory information the student needs.

			Name	Type	Generated Value

a1	integer	5
b1	integer	2
c1	integer	6

			Name	Type	Generated Value

a	list	[ 5, 5, 5, 10, 11 ]
b	list	[ 5, 5, 9, 7, 4 ]
c	list	[ 3, 2, 8, 6, 8 ]
d	list	[ 29, 4, 30, 17, 14, 15 ]
f	list	[ 9, 15, 11, 9, 2, 4, 15 ]

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$\var{c[0]}x+\var{c[1]}x+\var{c[2]}x=$ Unnamed gap

Advice

When simplifying expressions, only terms of the same type or like terms can be added together.

Algebraic symbols or letters can be added together provided that they are raised to the same power. For example, we can add $x^2+x^2=2x^2$, but we cannot collect both $x^2$ and $x$ into one term.

\[
\begin{align}
\var{c[0]}x+\var{c[1]}x+\var{c[2]}x&=(\var{c[0]}+\var{c[1]}+\var{c[2]})x\\
&=\simplify{({c[0]}+{c[1]}+{c[2]})}x
\end{align}
\]
