Question

x3-ax+bx-ab के गुणनखण्ड कीजिए।

Answer 1

The required answer is (x + a)(x² - ax + b)

Step-by-step explanation:

Given,

x³ - ax + bx + ab

=> x(x² - a) + b(x + a)

=> x(x + a)(x - a) + b(x + a)

Using (a² - b²) = (a + b)(a - b)

=> (x + a)[x(x - a) + b]

=> (x + a)(x² - ax + b)

Hence, the required answer is (x + a)(x² - ax + b)
