Question

(x + a) and (x-b) are the factors of
​

Answer 1

Answer:

x² + (a + b)x + ab

Step-by-step explanation:

Given : (x + a) and (x + b) are factors.

If we multiple them, we get the polynomial of which these are factors.

→ (x + a)(x + b)

→ x(x + b) + a(x + b)

→ x² + bx + ax + ab

→ x² + (a + b)x + ab

Answer 2

Answer:

(x+a) (x - a )

= x^2 - a^2

{ (a + b ) ( a - b ) = a^2 - b^2}
