I see several quadratic equations in the image you've uploaded. I'll list and solve them one by one.

1. Equation 1:

$x^2 - 5x + 9 = 0$

This is a standard quadratic equation, which we can solve using the quadratic formula: $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$ where $a = 1$, $b = -5$, and $c = 9$.

Let's calculate this.

2. Equation 2:

$4x^2 + 8x - 60 = 0$ This is also a quadratic equation. Here $a = 4$, $b = 8$, and $c = -60$. We can solve it using the quadratic formula or factoring.

3. Equation 3:

$2x^2 - 2 - 3x = 0$ Rearranging it in standard form: $2x^2 - 3x - 2 = 0$ Now, $a = 2$, $b = -3$, and $c = -2$.

4. Equation 4:

$36x^2 + 25 = 60x$ Rearranging: $36x^2 - 60x + 25 = 0$ Here $a = 36$, $b = -60$, and $c = 25$.

Let me solve these equations step-by-step using the quadratic formula.Here are the solutions for each equation:

1. $x^2 - 5x + 9 = 0$:

This equation has complex solutions: $x_1 = 2.5 + 1.66i, \quad x_2 = 2.5 - 1.66i$

2. $4x^2 + 8x - 60 = 0$:

The solutions are: $x_1 = 3.0, \quad x_2 = -5.0$

3. $2x^2 - 3x - 2 = 0$:

The solutions are: $x_1 = 2.0, \quad x_2 = -0.5$

4. $36x^2 - 60x + 25 = 0$:

This equation has one real solution (a repeated root): $x_1 = x_2 = 0.83$

Would you like more details or have any specific questions on these solutions?

Tip: Always check the discriminant first to know if you'll have real or complex solutions.
