Question

x²+3x+1=(x-2)²Check whether the following are quadratic equation
​

Answer 1

Answer:

no it is not

Step-by-step explanation:

x2 + 3x + 1 = x2 - 4x + 4

7x = 3

since the degree is 1 of the above equation hence it is linear equation and not quadratic equation.

hope this helps you...

Answer 2

Answer:It is not quadratic equation

Step-by-step explanation:x^2+3x+1=(x-2)^2

(a-b)^2=a^2+b^2-2ab

x^2+3x+1=x^2+4-4x

equation come into one side

x^2+3x+1-x^2-4+4x=0 (-x^2 &+x^2 are cancelled)

7x-3=0

It is not quadratic equation
