Question statement

For the following, leave the numbers as is, do not put into lowest form as these are algebra expressions:

For example:

When you simplify the equation and the answer is $3x -6$ , leave it as that, do not answer $3(x - 2)$ .

Give any introductory information the student needs.

Gap-fill

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

$\var{num1p[0]}(\var{num1p[1]}x + \var{num1p[2]}) \var{num1n[0]}(\var{num1p[3]} \var{num1n[1]}x) + \var{num1p[4]}$

Unnamed gap

Advice

Remove the brackets and gather the x terms together and also the number terms together.

When in fraction form, get the lowest common multiple (LCM), and multiply the top line by how many times the divisor goes into the LCM.

Rule for multiping out brackets:

(a $x$ - b)(c $x$ + d) = (a * c) $x^2$ + ((a * d) + ((-b) *c))) $x$ + ((-b) * d)

Rule for squaring brackets:

(-a $x$ + b) $^2$ = (-a * -a) $x^2$ + (2 * (-a) *b) $x$ + (b * b)

Give a worked solution to the whole question.
