Step 1/2 We are given a quadratic equation $2x^2 + mx + 16 = 0$. The roots of this equation are $\alpha$ and $\beta$, with $\alpha = 2\beta$ and both $\alpha$ and $\beta$ are positive. We know that the sum of the roots of a quadratic equation $ax^2 + bx + c = 0$ is given by $-\frac{b}{a}$, and the product of the roots is given by $\frac{c}{a}$. So, for our equation, we have Sum of roots $\alpha + \beta = -\frac{m}{2}$ Product of roots $\alpha \cdot \beta = \frac{16}{2} = 8$ Now, we can use the given relationship between $\alpha$ and $\beta$ to find the value of $m$. Since $\alpha = 2\beta$, we can substitute this into the sum of roots equation $2\beta + \beta = -\frac{m}{2}$ $3\beta = -\frac{m}{2}$ Now, we can substitute the product of roots equation into this equation $\alpha \cdot \beta = 8$
