Part (ai) · 2 marks
Expand 3(2d − 3) + 4(d + 1) and simplify the result.
- 16d − 9 + 4d + 4
- 2= 10d − 5
Answer10d − 5 or 5(2d − 1)
Part (aii) · 2 marks
Expand and simplify the product (x − 4)(x − 3).
- 1x² − 3x − 4x + 12
- 2= x² − 7x + 12
Answerx² − 7x + 12
Part (b) · 1 mark
Factorise the expression 8p − 3pq.
- 18p − 3pq = p(8 − 3q)
Answerp(8 − 3q)
