Show answer and explanation
Correct Answer
A. x² - 9x + 14 = 0 / x² - 9x + 14 = 0
ExplanationStep 1: Equation is x² - (sum)x + product = 0. Step 2: Sum is 9 and product is 14 so x² - 9x + 14 = 0. Step 3: Use sum and product while forming equation from roots.
Step 1: Equation x² - (sum)x + product = 0 होती है। Step 2: sum 9 और product 14 है इसलिए x² - 9x + 14 = 0। Step 3: Roots से equation बनाते समय sum और product लें।
