Question

Yiii) Given that (x - a) (x - 5)(x - c) = x3 - (a + b + c)x2 + (ab + bc + ca)x + abc, find
the product (x - 1)(x - 2)(x - 3)
​

Answer 1

Answer:

x^3 - 6x^2 + 11x - 6

Explanation:

(x - 1) (x - 2) (x - 3)

= (x^2 - 2x - x + 2) (x - 3)

= (x^2 - 3x + 2) (x - 3)

= x^3 - 3x^2 - 3x^2 + 9x + 2x - 6

= x^3 - 6x^2 + 11x - 6
