Question

If $5x^{2} + 3x + 100 = 0$ are distinct roots of the equation

$3x^{2} - 5x + 100 = 0$ then.

• A. $5x^{2} - 3x - 100 = 0$
• B. $5x^{2} - 3x - 100 = 0$
• C. $k(6x^{2} + 3) + rx + 2x^{2} - 1 = 0$
• D. $6k(2x^{2} + 1) + px + 4x^{2} - 2 = 0$

Answer 1

Answer: (D)

$6k(2x^{2} + 1) + px + 4x^{2} - 2 = 0$

Answer 2

Since quadratic equation $x^{2} + y^{2} = 25,\mspace{6mu} xy = 12$has three distinct roots so it must be an identity.

So $x =$.
