How are quadratic equations different from linear equations
Answers
Differences Between Quadratic & Linear Equations. A linear equation in two variables doesn't involve any power higher than one for either variable. ... A quadratic equation, on the other hand, involves one of the variables raised to the second power. It has the general form y = ax2 + bx + c.
hope it helps you mark this answer as brainlist and follow me.
In quadratic equation the highest power of the variable, i.e., the degree is 2. it is also the reason due to which it is written in the form of ax^2 + bx + c where a, b, c are real numbers and c is not equal to zero.
eg. 2x^2-3x+4
4u^2-2u+8
whereas in linear equation, the highest power of the variable ,i.e., the degree is 1. this is the reason that it is written in the form of ax + b where a and b are real numbers and b is not equal to zero.
eg. 2x+1
