Quadratic Equations are equations of the form ax^2 + bx + c = 0 where a, b and c are real numbers and a \neq 0. Depending on the form of the equation, you can solve for x by extracting the quare root, factoring, or using the quadratic formula.This type of equation appears in various problems that involves multiplication and usually appears in the Civil Service Exams.

The following series details the method and strategies in solving problems involving quadratic equations.

How to Solve Quadratic Word Problems Part 1 is about solving problems involving consecutive integers. In this problem, the product of consecutive numbers is given and factoring was used to solve the problem. 

How to Solve Quadratic Word Problems Part 2 is about solving age problems. Just like in the first part, the product of two ages are given and factoring was used to solve the problem.

How to Solve Quadratic Word Problems Part 3 is about equations to solve area problems. In this problem, a walk is created around a rectangular garden. Both the areas of the garden and the walk is given and the width of the walk was solved.

We will be discussing more sample problems in the future. Enjoy learning!
