Explanation opens after your attempt
Correct Answer

B. (2)

Step 1

Concept

(x-2-6x+8=(x-4)(x-2)) so the other root is (2). Use the given root to find the other factor.

Step 2

Why this answer is correct

The correct answer is B. (2). (x-2-6x+8=(x-4)(x-2)) so the other root is (2). Use the given root to find the other factor.

Step 3

Exam Tip

(x-2-6x+8=(x-4)(x-2)) इसलिए दूसरा मूल (2) है। दिए गए एक मूल से दूसरा गुणनखंड खोजें।
