# CLASS-10QUADRATIC EQUATIONS - INTRODUCTION OF PROBLEM SOLVING

In the previous chapter we have discussed about the method of solving various types of quadratic equations either by factorization or by using quadratic formulae.

Now, we would like to learn to apply these methods to solve certain word problems and determine unknown values, by forming quadratic equations from the information given and solving them. The problems may be based on numbers, ages, time and work, time and distance, mensuration, etc.

Method of Solving Problems on Quadratic Equations

Step.1) Read the given problem carefully and assume the unknown quantity to be ‘x’.

Step.2) Translate the given statement and form a quadratic equation in ‘x’

Step.3) Solve for ‘x’

There are some segment of problem has been discussed as an example for your better understanding -

a) Problem on Numbers,

b) Problem on Ages,

c) Problem on Time & Distance,

d) Problem on Time & Work,

e) Problem on Mensuration,

f) Problem on Geometrical Figures,

g) Miscellaneous Problem,
