To solve question 2 involving the inequality:

$\frac{x-2}{x^2} \leq \frac{x+1}{x-3}$

we proceed step by step:

Step 1: Combine into one rational inequality

First, bring the terms to one side by subtracting the right-hand side:

$\frac{x-2}{x^2} - \frac{x+1}{x-3} \leq 0$

To combine these fractions, find the common denominator, which is $x^2(x-3)$. Then rewrite both terms:

$\frac{(x-2)(x-3)}{x^2(x-3)} - \frac{x^2(x+1)}{x^2(x-3)} \leq 0$

Step 2: Simplify the numerator

Combine the numerators over the common denominator:

$\frac{(x-2)(x-3) - x^2(x+1)}{x^2(x-3)} \leq 0$

Now expand the terms in the numerator:

• $(x-2)(x-3) = x^2 - 3x - 2x + 6 = x^2 - 5x + 6$,
• $x^2(x+1) = x^3 + x^2$.

So the numerator becomes:

$(x^2 - 5x + 6) - (x^3 + x^2).$

Simplify further:

$x^2 - 5x + 6 - x^3 - x^2 = -x^3 + 6 - 5x.$

Thus the inequality is now:

$\frac{-x^3 - 5x + 6}{x^2(x-3)} \leq 0.$

Step 3: Determine critical points

The numerator and denominator determine the points where the function equals $0$ or is undefined:

1. Numerator: $-x^3 - 5x + 6 = 0$, Solve for $x$ (roots of a cubic equation).

2. Denominator: $x^2(x-3) = 0$, The denominator is undefined at $x = 0$ and $x = 3$.

Critical points are the solutions to both the numerator and denominator.

Step 4: Sign analysis

Break the number line into intervals around the critical points and test the sign of the expression in each interval. Remember to exclude points where the denominator is zero.

Final Answer

The solution will include the intervals where the inequality holds true, considering all critical points and undefined values. This is often written as a union of intervals.
