Question: make me a test abt that
1. The problem is to create a test based on the previous topic discussed.
2. Since the user did not specify the exact topic, I will assume it relates to algebraic expressions and solving equations.
3. Here is a sample test with 3 questions:
1) Solve for $x$: $$2x + 5 = 15$$
2) Simplify the expression: $$\frac{3x^2 - 6x}{3x}$$
3) Factor the quadratic: $$x^2 - 5x + 6$$
4. Each question tests fundamental algebra skills: solving linear equations, simplifying rational expressions, and factoring quadratics.
5. The answers are:
1) $$2x + 5 = 15 \Rightarrow 2x = 10 \Rightarrow x = 5$$
2) $$\frac{3x^2 - 6x}{3x} = \frac{3x(x - 2)}{3x} = \cancel{3x} (x - 2)/\cancel{3x} = x - 2$$
3) $$x^2 - 5x + 6 = (x - 2)(x - 3)$$
This test covers key algebra concepts and can be used for practice or assessment.
