For which polynomial is (x=2) a zero?

Explanation opens after your attempt
Correct Answer

A. (p(x)=x-2)

Step 1

Concept

(p(2)=2-2=0), so (x=2) is its zero. To test a zero, substitute and check for (0).

Step 2

Why this answer is correct

The correct answer is A. (p(x)=x-2). (p(2)=2-2=0), so (x=2) is its zero. To test a zero, substitute and check for (0).

Step 3

Exam Tip

(p(2)=2-2=0), इसलिए (x=2) इसका शून्य है। शून्य जांचने के लिए मान रखकर (0) देखें।
