Limit (11-11e^x)/x. Factoring Quadratics: The Hard Case. Factoring Quadratics: The Hard Case: The Modified "a-b-c" Method, or "Box" (page 2 of 4) Sections: The simple case, The hard case, The weird case To factor a "hard" quadratic, we have to handle all three coefficients, not just the two we handled in the "easy" case, because the leading coefficient (the number on the x2 term) is not 1.
The first step in factoring will be to multiply "a" and "c"; then we'll need to find factors of the product "ac" that add up to "b". Exponential Word Problems.
