The expression in the image is:

$x^2 - 3x + 10$

This is a quadratic expression, but it cannot be factored into real numbers since its discriminant is negative. Let's analyze it step by step:

1. Standard Form: The expression is already in the standard quadratic form $ax^2 + bx + c$, where:

   • $a = 1$
   • $b = -3$
   • $c = 10$

2. Discriminant: The discriminant $\Delta$ is given by: $\Delta = b^2 - 4ac$ Substituting the values: $\Delta = (-3)^2 - 4(1)(10) = 9 - 40 = -31$ Since the discriminant is negative ($\Delta = -31$), the quadratic does not have real roots, only complex ones.

3. Complex Roots: The roots of the quadratic equation can be found using the quadratic formula: $x = \frac{-b \pm \sqrt{\Delta}}{2a}$ Substituting the values: $x = \frac{3 \pm \sqrt{-31}}{2} = \frac{3 \pm i\sqrt{31}}{2}$

   The roots are complex: $x_1 = \frac{3 + i\sqrt{31}}{2}, \quad x_2 = \frac{3 - i\sqrt{31}}{2}$
