यदि \(A={x:x\in \mathbb{N}, x^2-5x+6=0}\) है तो कौन सा समुच्चय (A) के बराबर है?

If \(A={x:x\in \mathbb{N}, x^2-5x+6=0}\) then which set is equal to (A)?

Explanation opens after your attempt
Correct Answer

A. ({2,3})

Step 1

Concept

(x-2-5x+6=(x-2)(x-3)), so the solutions are (2,3). First solve the equation and then write the set.

Step 2

Why this answer is correct

The correct answer is A. ({2,3}). (x-2-5x+6=(x-2)(x-3)), so the solutions are (2,3). First solve the equation and then write the set.

Step 3

Exam Tip

(x-2-5x+6=(x-2)(x-3)) है इसलिए हल (2,3) हैं। पहले समीकरण हल करें फिर समुच्चय लिखें।
