Question

Which of the following is not a quadratic equation?

A. x -3/x=4
B. 3x-5/x=x^2
C. x+1/x=3
D. x^2-3=4x^2-4x

Pls explain properly

Answer 1

Answer:

Identify the values of a, b, and c in the standard form of the equation 3x + x2 = 6.

A) a = 3, b = 1, c = 6

B) a = 1, b = 3, c = 6

C) a = 1, b = 3, c = −6

D) a = 3, b = 1, c = −6

Answer 2

Answer:

B. 3x - 5/x = x^2

Step-by-step explanation:

Because after taking LCM we get

#(3x^2 -5)/x = x^2

#(3x^2 -5)= x^2 * x

#3x^2 -5=x^3

#x^3-3x^2 + 5 +0

So now this is a cubic equation

not a quadratic equation
