Marks
17 / 20
A strong paper. Careful checking will take you to full marks.
You understand the factor and remainder theorems and use identities well. The three marks you lost came from signs and adding, not from the ideas themselves.
What went well
Factor theorem
You tried x = 1 and found the first factor of the cubic straight away.
Identities and splitting the middle term
Questions 7 and 8 were complete, with every step shown.
What to work on
Signs
In questions 3 and 9, a sign changed partway through and cost a mark each.
Checking the final addition
In question 6 you substituted correctly, but −1 + 3 − 3 + 1 adds up to 0, not 2.
Next steps
- After factorising, multiply the brackets back out. You should get the expression you started with.
- When you find a zero, put it back into the polynomial. The answer should come to 0.
- With a long sum, add one term at a time and write down each running total.
