TOPIC 2
ALGEBRAIC EXPRESSIONS

1. Given that y = 2x – z
x + 3z express x in terms of y and z
2. Simplify the expression
x – 1 - 2x + 1
x 3x
Hence solve the equation
x – 1 - 2x + 1 = 2
x 3x 3
3. Factorize a2 – b2
Hence find the exact value of 25572 - 25472
4. Simplify p2 – 2pq + q2
P3 - pq2 + p2 q –q3
5. Given that y = 2x – z, express x in terms of y and z.
Four farmers took their goats to a market. Mohammed had two more goats as Koech had 3 times as many goats as Mohammed, whereas Odupoy had 10 goats less than both Mohammed and Koech.
(i) Write a simplified algebraic expression with one variable, representing the total number of goats.
(ii) Three butchers bought all the goats and shared them equally. If each butcher got 17 goats, how many did odupoy sell to the butchers?
6. Factorize completely 3x2 – 2xy – y2
7. Solve the equation
1 = 5 -7
4x 6x
8. Simplify
a + b
2(a+ b) 2(a-b)

9. Factorize completely 28x2 + 3x -1
10. Three years ago, Juma was three times as old. As Ali in two years time, the sum of their ages will be 62. Determine their ages
