Question

For the quadratic equation : $9x^2+4x+15$ = 0, product of the roots = .

• A. $\frac{5}{3}$
• B. -$\frac{5}{3}$
• C. $\frac{15}{4}$
• D. $\frac{4}{15}$

Answer 1

The correct option is A $\frac{5}{3}$

For a quadratic equation given by $a{x}^2+bx+c$ = 0, the product of the roots is given by $\frac{c}{a}$.
Here, a = 9, b = 4, c = 15.
Hence, the product of the roots = $\frac{c}{a}$ = $\frac{15}{9}$ = $\frac{5}{3}$.
