Multiply (x

^{2}– 3x + 1) by (x – a)-
**A.**

x^{3}– (3 + a) x^{2}+ (1 + 3a)x – a -
**B.**

x^{3}– (3 – a)x^{2}+ 3ax – a -
**C.**

x^{3}– (3 – a)x^{2}– (1 = 3a) – a -
**D.**

x^{3}+ (3 – a)x^{2}+ (1 + 3a) – a

##### Correct Answer: Option A

##### Explanation

(x^{2} – 3x + 1)(x – a) = x^{3} – 3x^{2} + x – ax^{2} + 3ax – a

= x^{3} – (3 + a) x^{2} + (1 + 3a)x – a
