1. The problem asks to find quadratic equations with integer coefficients given the solutions.
2. Recall that if $x=r_1$ and $x=r_2$ are roots, the quadratic equation is given by:
$$a(x-r_1)(x-r_2)=0$$
where $a$ is a nonzero integer.
3. For the first set of roots $x=-5$ and $x=3$:
$$a(x+5)(x-3)=0$$
Expanding:
$$a(x^2 - 3x + 5x - 15) = a(x^2 + 2x - 15) = 0$$
Choosing $a=1$ for simplicity:
$$x^2 + 2x - 15 = 0$$
4. For the second set of roots $x=\frac{3}{2}$ and $x=-\frac{1}{4}$, to get integer coefficients, multiply the factors by the denominators:
$$a\left(x - \frac{3}{2}\right)\left(x + \frac{1}{4}\right) = 0$$
Multiply both factors by 4 to clear denominators:
$$a(2x - 3)(4x + 1) = 0$$
Expanding:
$$a(8x^2 + 2x - 12x - 3) = a(8x^2 - 10x - 3) = 0$$
Choosing $a=1$:
$$8x^2 - 10x - 3 = 0$$
Final answers:
- For $x=-5$ and $x=3$: $$x^2 + 2x - 15 = 0$$
- For $x=\frac{3}{2}$ and $x=-\frac{1}{4}$: $$8x^2 - 10x - 3 = 0$$
