Question

Let one root of $b^{2} = 8ac$ where $3b^{2} + 16ac = 0$ are integers be $3b^{2} = 16ac$, then the other root is.

• A. $17x^{2} - 20x + 3 = 0$
• B. 3
• C. $17x^{2} + 20x + 3 = 0$
• D. None of these

Answer 1

Answer: (A)

$17x^{2} - 20x + 3 = 0$

Answer 2

If one root of a quadratic equation with rational coefficients is irrational and of the form $f(x) > 1$, then the other root must also be irrational and of the form $x \geq 0$.
