Consider the provided question,

Quadratic equations are equations of degree 2. Linear equations have only one degree but quadratic have 2 degrees.

The general form of the quadratic and linear equation is given as quadratic equation: \(y=ax^2+bx+c\)

linear equation:y=ax+b

where a,b,c are the constants

Quadratic equations are compulsory to be learnt as they extend the knowledge and applications more than linear equations.

Since, a lot of the physics equation can be modeled through quadratic equations like throwing a ball.

In the business world, sometimes the business people are interested only in deviations in absolute value. In other words, they are not bothered whether more or less and how much it varies on either side. In those cases, quadratic being square provides them with good idea.

All quadratic equations have either minimum or maximum thus helps business people to find optimum level. Also by learning quadratic only we come across imaginary and complex roots. Thus our knowledge is broadened by learning discriminant of quadratic equations and how it controls the nature of roots. Also learning quadratic helps us to solve for equations of higher degrees using factorization, synthetic division, etc.
