Please refer to the picture for explanation.

Answer 2

The value of a is equal to 1.

Step-by-step explanation:

Given,

(x - 1) is the factor of the polynomial $2x^2 - 2a$.

To find,  the value of a = ?

∴ x - 1 = 0

⇒ x = 1

Put x = 1 in the given polynomial, we get

$2(1)^2 - 2a = 0$

⇒ 2(1) - 2a = 0

⇒ 2a = 2

⇒ a = 1

Thus, the value of a is equal to 1.
