Question in Core Foundation Maths
Solve for x and y: a1x+b1y=c1a2x+b2y=c2
The included video describes a more direct method of solving when, for example, one of the equations gives a variable directly in terms of the other variable.

Question in Demos
Customised for the Numbas demo exam
Factorise x2+cx+d into 2 distinct linear factors and then find ∫ax+bx2+cx+ddx,a≠0 using partial fractions or otherwise.
Video in Show steps.

Question in Bill's workspace
Solve ax+b=fg(cx+d) for x.
A video is included in Show steps which goes through a similar example.

Question in Bill's workspace
The derivative of ax2+bcx2+d is g(x)(cx2+d)2. Find g(x).
Contains a video solving a similar quotient rule example. Although does not explicitly find g(x) as asked in the question, but this is obvious.

Question in Bill's workspace
Express loga(xcyd) in terms of loga(x) and loga(y). Find q(x) such that fgloga(x)+loga(rx+s)−loga(x1/t)=loga(q(x)).
There is a video included explaining the rules of logarithms by going through simplification of logs of numbers rather than algebraic expressions.
-
Question in Bill's workspace
Expand (ay+b)(cy+d)(py+q).
Includes a video expanding three brackets, however uses the variable x rather than y.
-
Question in Bill's workspace
Find p and q such that ax2+bx+c=a(x+p)2+q.
Hence, or otherwise, find roots of ax2+bx+c=0.
Includes a video which shows how to solve a quadratic by completing the square.

Question in Bill's workspace
Differentiate cos(eax+bx2+c).
Contains a video solving a similar example.
