Show answer and explanation
Correct Answer
A. x² - 21x + 104 = 0
ExplanationStep 1: From roots the equation is x² - (sum)x + product = 0. Step 2: Sum is 21 and product is 104 so option A is correct. Step 3: Find sum and product while forming equation from roots.
Step 1: Roots से equation x² - (sum)x + product = 0 बनती है। Step 2: sum 21 और product 104 है इसलिए option A सही है। Step 3: Roots से equation बनाते समय sum और product निकालें।
