Question

Which of the following is not a linear equation in two variables?
       (i) px + qy + c = 0 (ii) ax 2  + bx + c = 0 (iii) 3x + 2y = 5

Answer 1

Hi there!

⏩ General form of Linear Eqn. in two variables: ax + by + c = 0

Whereas,
⏩General for of Quadratic Eqn.: ax² + bx + c = 0

ATQ,

Option (ii) does not satisfy General form of Linear eqn. in two variables.

Hence,
Option (ii) is Correct ...

Cheers!
