Question statement

Du kan skrive inn algebraiske uttrykk tekstboksene. For eksempel kan du skrive a^3 og få $a^3$ og enten 2*x-3*y eller bare 2x-3y og få $2x-3y$ . Det anbefales at dere bruker '*' mellom variabler, for at NUMBAS skal tolke det dere skriver riktig. Skriv for eksempel a*b heller enn ab, og x^2*y heller enn x^2y for å få $x^2y$ .

Ved siden av input-boksen ser dere hvordan NUMBAS tolker det dere skriver.

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.

Løs opp parentesen og trekk sammen

$\var{a1}(\var{a2}x+\var{a3})-\var{a4} =$

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.
