So, what exactly is a Quadratic Equation?
Any quadratic equation contains only the powers of x that are in nature non-negative integers, and therefore they are called a polynomial equation. In particular, it is any second-degree polynomial equation, having the greatest power of 2.
How do you solve a quadratic equation?
Any quadratic equation with real or complex coefficients will always have two solutions, which are known as roots. These two solutions can or cannot be distinct, and they may or may not be real.
Why and what do you need to solve this chapter?
In the year 2017, quadratic equations had a great weightage of marks with a total of 13 marks. Therefore, the students need to have a thorough and complete understanding of the topic.
Numerical NCERT solutions:
The area of a rectangular piece of land is 628m2. The length of the given rectangular piece of land (in meters) is one more than twice its breadth. Help us find the length and breadth of the piece of the given land.
Solution: Let us consider,
Breadth of the rectangular plot = x m
Thus, the length of the plot = (2x + 1) m.
As we know,
Area of rectangle = length × breadth = 628 m2
Putting the value of length and breadth of the plot in the formula, we get,
(2x + 1) × x = 628
⇒ 2x2 + x =628
⇒ 2x2 + x – 628 = 0
Therefore, the length and breadth of plot, satisfies the quadratic equation, 2x2 + x – 628 = 0, which is the required representation of the problem mathematically.
There are two integers given, the product of the given two consecutive positive integers is 408, find out what the two consecutive integers are.
Let us consider,
The first integer number = x
Thus, the next consecutive positive integer will be = x + 1
Product of two consecutive integers = x × (x +1) = 408
⇒ x2 + x = 408
⇒ x2 + x – 408 = 0
Therefore, the two integers x and x+1, satisfies the quadratic equation, x2 + x – 408 = 0, which is the required representation of the problem mathematically.
A train is traveling at a uniform speed for a distance of 540 kilometers. Imagine if the train had been 9 km/hr less, then it would have taken?
Let us consider,
The speed of train = x km/h
And
Time taken to travel 540 km = 540/x km/hr.
As per second condition, the speed of train = (x – 9) km/h
Also given, the train will take 3 hours to cover the same distance.
Therefore, time taken to travel 540 km = (540/x) + 3 km/h
As we know,
Speed = Distance/Time
Therefore,
Distance = Time x Speed
(x – 9) {(540/x) + 3} = 540
⇒ 540 + 3x – 4860/x –27= 540
3x – 4860/x –27= 540-540
⇒ 3x – 4860/x = 27
⇒ x2 – 9x – 1620 = 0
Therefore, the speed of the train, satisfies the quadratic equation, x2 – 9x – 1620, which is the required representation of the problem mathematically.
