Expert Answer:

Dear Student,
 
The name Quadratic comes from "quad" meaning square, because the variable gets squared like x2.
It is also called an equation of degree "2".
 
The Satandard form of a quadratic equation can be written as
ax2 + bx + c = 0
 Where, ab and c are known values. a can't be 0.
"x" is the Variable or unknown (you don't know it yet).
 
 
Below i have mentioned some example of Quadratic equation
 
2x2+5x+3=0
In this case a=2b=5 and c=3
 
x2-3x+1=0
In this case a=1b=-3 and c=1
 
 
 
Thanks and Regards
