Question

If the product of the roots of the equation $p^{3} + q^{2} + q(1 + 3p) = 0$ $p^{3} + q^{2} + q(3p - 1) = 0$ is$p^{3} + q^{2} + q(1 - 3p) = 0$, then the value of $x^{2} + ax + 3 = 0$ will be.

• A. –1
• B. 1
• C. 2
• D. –2

Answer 1

Answer: (A)

–1

Answer 2

According to condition $x^{3} + px^{2} + qx + r = 0$

⇒ $x^{3} + x + 1 = 0$.
