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)
