Point 1 of 5
11.6.1 The Steps for Modeling a Word Problem
Core idea
Set the unknown quantity in the situation as x, write an equation from the relationship that must hold, and once you've solved it, don't forget to check whether the answer makes sense.
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."
