If the roots of a quadratic equation are 1 and 6 then which equation is correct?

A. x² - 7x + 6 = 0 / x² - 7x + 6 = 0

Step 1: If roots are α and β then equation is x² - (sum)x + product = 0. Step 2: Sum is 7 and product is 6 so equation is x² - 7x + 6 = 0. Step 3: Find sum and product while forming equation from roots.

Step 1: Roots α और β हों तो equation x² - (sum)x + product = 0 होती है। Step 2: sum 7 और product 6 है इसलिए equation x² - 7x + 6 = 0 है। Step 3: Roots से equation बनाते समय sum और product निकालें।
