Students need to use a pronumeral to represent the unknown number They then need to write an equation and solve it to find the value of the unknown number.In this lesson we present some typical word problems that may be solved using quadratic equations.

If Andrew works alone, he can complete this job in days.

Thus, in one single day Andrew covers part of the roof area, while Bill covers part of the roof area. Two tubes, working together, can fill the reservoir with the liquid in 12 hours.

Quadratic equations are also needed when studying lenses and curved mirrors.

And many questions involving time, distance and speed need quadratic equations.

To simplify this equation, multiply both sides by , then transfer all terms from the right side to the left with the opposite signs, collect the common terms and adjust the signs. Solution Let be number of hours to fill the reservoir using the smaller tube only.

Then is the time in hours to fill the reservoir using the larger tube only.

The easiest way to explain this would be using an example. Let us imagine that you are working as a computer programmer in a company that makes computer games.

You are getting paid 50$ per hour and at the end of the day, you earned 400$.

Therefore, it is important that you feel comfortable using them.
