Question in Transition to university
Factorise a quadratic expression of the form $x^2+akx+bk^2$ for $x$, in terms of $k$. $a$ and $b$ are constants.

Question in Transition to university
This question tests the students ability to factorise simple quadratic equations (where the coefficient of the x^2 term is 1) and use the factorised equation to solve the equation when it is equal to 0.

Question in Transition to university
The amount of money a person gets on their birthday follows an arithmetic sequence.
Calculate the amount on a given birthday, then calculate the sum up to that point.

Question in Transition to university
Differentiate between linear and quadratic sequences and arithmetic and geometric sequences through a series of multiple choice questions. Spot different patterns in sequences like the triangle sequence, square sequence and cubic sequence and then use this pattern to find the next three terms in each of the sequences.

Question in Transition to university
Given the first four terms of a quadratic sequence, write down the formula for the $n^\text{th}$ term.

Question in Transition to university
Given the first three terms of a sequence, give a formula for the $n^\text{th}$ term.
In the first sequence, $d$ is positive. In the second sequence, $d$ is negative.

Question in Transition to university
Factorise three quadratic equations of the form $x^2+bx+c$.
The first has two negative roots, the second has one negative and one positive, and the third is the difference of two squares.

Question in Transition to university
Factorise a quadratic equation where the coefficient of the $x^2$ term is greater than 1 and then write down the roots of the equation

Question in Transition to university
Find the common ratio of a given geometric sequence, write down the formula for the nth term and use it to calculate a given term in the sequence.
