I managed to get the correct answers to 6(i) & (ii). It was a miscalculation on my part.

Seeing thie equation factorised, first is to expand it to get the quadratic equation. Then similar with 5c, make the constant variable on the right hand side of the equation

Use the same method as the other 2 questions, just think of the variable a, is a number. Is the answer correct?
