Musa's copy of 3 Expand brackets

Question 1

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.

$\var{c[0]}x+\var{c[1]}x+\var{c[2]}x=$ interpreted as $\displaystyle{}$ Expected answer:interpreted as $\displaystyle{23 x}$

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.

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