Was requested to provide solution to "Sec 1 q 8" and am not sure what this refers to?
SEC A Q8 is a differentiation question which we haven't covered yet. The trick in this question is in the first step i.e. multiplying by (x + 1)^2 After that you could expand and solve the quadratic giving the solutions -2 and -1. The region test below could also be done by considering the quadratic graph. See examples in uploaded video below. Though this question is mostly relating to exponential equations part b is a differentiation question which we have not covered yet.
