If A = {x : x² - 5x + 6 = 0} and B = {2 3 4} then what is A ∩ B?
यदि A = {x : x² - 5x + 6 = 0} और B = {2 3 4} है तो A ∩ B क्या होगा?
Show answer and explanation
Correct Answer
B. {2 3} / {2 3}
ExplanationStep 1: First factor x² - 5x + 6 = 0. Step 2: The roots are 2 and 3 so A = {2 3}. Step 3: Intersection contains elements common to both sets.
Step 1: पहले समीकरण x² - 5x + 6 = 0 को factor करें। Step 2: roots 2 और 3 हैं इसलिए A = {2 3}। Step 3: intersection में वही तत्व आते हैं जो दोनों sets में हों।
