1

Write down an algebraic expression for five more than eight multiplied by x

8x + 5

2

A boy went shopping with £A. He spent £B. How much has he got left?

£(A - B)

3

Simplify

5t x 3t

15t2

4

Simplify

3i + 2k – i + k

2i + 3k

5

Simplify

5x2 + 6x2 – 7y + 4 + 2y

11x2 – 5y + 4

6

Expand

2(5 - 3w)

10 - 6w

7

Expand

3p(4p3 - 5m)

12p4 - 15mp

8

Expand and Simplify

3(4 + t) + 2(5 + t)

22 + 5t

Reasoning:

12 + 3t + 10 + 2t

=22 + 5t

9

Expand and Simplify

t(3t – 4) + 3t(3 + 2t)

9t2 + 5t

Reasoning:

3t2 – 4t + 9t + 6t2

= 9t2 + 5t

10

Factorise

6m + 12t

6(m + 2t)

Reasoning:

The highest common factor of 6 and 12 is 6. There are no common letters.

11

Factorise

6p2 – 9pt

3p(2p – 3t)

Reasoning:

The highest common factor of 6 and 9 is 3. Both terms have a p as a common letter.

12

Factorise

8ab2 + 2ab – 4a2b

2ab(4b + 1 – 2a)

Reasoning:

The highest common factor of 8, 2 and 4 is 2. All the terms have an a and a b in common.
