Question

Which of the following is a non-linear equation?

i) x/3=12
ii) x+1=6
iii) x+y+z=17
iv) xy+x/y=3


​

Answer 1

iv ; xy + x/y = 3

Explanation:

A non linear equation is one in which there is no product of two different variables or the same variable

What this mean is that we have the highest polynomial power as 1 or we simply have polynomials of degree 1

Looking at the given options, we can see the product xy

What this mean is that the polynomial is of degree 2 and that makes the equation a non linear as we have a polynomial of more than 1 degree
