PROBLEM ON QUADRATIC EQUATIONS –
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) First of all, we have to read the given problem carefully and assume the unknown quantity to be ‘x’.
Step.2) Then we need to translate the given statement and form a quadratic equation in ‘x’
Step.3) Then solve for ‘x’
