What is the independent term in the product of (x - 1) (x - 2) (x - 3)?
1 1
2 -6
3 3
4 6
Explanation:
-6 Opening the brackets and multiplying the terms, we get (x\(^{1}\)- 3x + 2) (x - 3) = x\(^{1}\) - 3x\(^{1}\) - 3x\(^{1}\) + 9x + 2x - 6 So the term not containing x is the independent term = -6

The sum of the coefficients in the terms of 2x\(^{1}\)y - 3xy\(^{1}\) + 4xy is:
1 -3
2 3
3 9
4 5
Explanation:
-3 B 3 As, the coefficient in the term 2x\(^{1}\)y = 2, the coefficient in the term -3xy\(^{1}\) = -3 and the coefficient in the term 4xy = 4. So, the sum of the coefficients in the terms of 2x\(^{1}\)y - 3xy\(^{1}\) + 4xy = 2 + (-3) + 4 = -3 + 6 = 3 Hence, the correct alternative is option (b).
