Answer 5th question with full solution
Answer properly

Answer 1

If a, b and c are the roots of any equation, then the required equation is

(x - a)(x - b)(x - c) = 0

So, similarly your required equation here is

=> (x -1)(x -(-1))(x - 3) = 0

=> (x - 1)(x + 1)(x - 3) = 0

=> (x² + x - x - 1)(x - 3) = 0

=> (x² - 1)(x - 3) = 0

=> (x³ - 3x² - x + 3) = 0

This is the required equation.

Hence, your answer is option (D)
