A rectangular garden has an area of 120 square feet. Its length is 2 feet more than twice its width. What are the dimensions?
Reasoning strategy
Let width be w, write w(2w + 2) = 120, then solve the quadratic.
Difficulty Practice Guide
Medium Grade 8 Quadratic Equations Word Problems
This page shows what medium practice should demand for grade 8 quadratic equations word problems. The goal is not a larger worksheet. The goal is to make the student's reasoning visible enough to choose the next better problem.
What Changes At This Difficulty
Add one meaningful reasoning layer so students must plan before calculating.
Expected structure: 3-4 step problem solving.
Vocabulary load: high with intentional distractors.
Reasoning depth: at least 3 relationship layers.
Student Work Signals
A good medium problem should expose the bottleneck
MathRoutine watches for whether the student understood the situation, wrote a useful setup, handled the calculation, and answered the exact question asked.
1
separate useful numbers from background details
2
complete a two-step setup
3
interpret the result with the correct unit
Sample Problems
A ball's height is h = -16t^2 + 64t + 5. At what time does it first reach 53 feet?
Reasoning strategy
Set the height equal to 53 and solve for the relevant positive time.
Why This Matters
The paid value is diagnosis, not answer lookup
Basic gives repeated targeted practice. Pro becomes useful when the student needs help understanding wording, recovering the setup, or seeing the same misconception return across attempts.
