Question

Multiply (x+a),(x+b) and (x+c).​

Answer 1

Answer:

(x + 1)(x + 2)(x + 3)

Solution:

We know that, (x + a)(x + b)(x + c) = x3

3

+ (a + b + c)x2

2

+ (ab + bc + ca)x + abc

Here, a = 1, b = 2 and c = 3

Therefore, the product = x3

3

+ (1 + 2 + 3)x2

2

+ (1 ∙ 2 + 2 ∙ 3 + 3 ∙ 1)x + 1 ∙ 2 ∙ 3

= x3

3

+ 6x2

2

+ 11x + 6.

Answer 2

Answer:

x^3 + bcx + ax^2 + abc

Step-by-step explanation:

Given,

(x+a) (x+b) (x+c)

= x × x × x + x × b × c + a × x × x + a × b × c (Just for understanding, not to be written actually)

= x^3 + bcx + ax^2 + abc (Answer)
