To construct an equation of a polynomial with the given conditions, let's outline the process based on each requirement:

Given Statements:

1. The degree is odd: This suggests the polynomial should have an odd degree, which generally means it will cross the x-axis an odd number of times.
2. The leading coefficient is positive: This means the polynomial will rise to positive infinity as $x$ approaches positive infinity.
3. The x-intercepts are $(-2, 0)$ and $(5, 0)$: These points indicate that the polynomial has factors of $(x + 2)$ and $(x - 5)$.
4. The y-intercept is $(0, -10)$: This tells us the constant or specific term that adjusts the polynomial vertically.

Step-by-step Solution:

1. Form the factors for the x-intercepts: Since the intercepts are at $(-2, 0)$ and $(5, 0)$, the factors are $(x + 2)$ and $(x - 5)$.

2. Determine the degree of the polynomial: To ensure an odd degree, we need at least one of the factors raised to an odd power. We will keep the degree simple by making it the first degree, resulting in: $P(x) = a(x + 2)(x - 5)$ where $a$ is a constant that we will determine.

3. Find the constant $a$ using the y-intercept: Plugging in the y-intercept point $(0, -10)$, we get: $P(0) = a(0 + 2)(0 - 5) = -10$ Simplifying this: $P(0) = a \cdot 2 \cdot (-5) = -10$ $-10a = -10$ $a = 1$

4. Construct the final equation: $P(x) = (x + 2)(x - 5)$ Expanding this: $P(x) = x^2 - 3x - 10$

Final Polynomial:

$P(x) = x^2 - 3x - 10$
