11.6 Quadratic Equations in Action and a Look Ahead
Point 2 of 5
11.6.2 Area and Geometry Problems
Core idea
Fencing a yard, paving a path, folding a box — the area relationship lines up into a quadratic equation, and a negative root usually has to be thrown out.
Module goal. Use quadratic equations to solve real problems about area, growth rates, and more, then carry the "equals" mindset toward the next stage's "not equals."
