Answer 2

Answer:

1) x - 4/x = 5

=> x² - 4x = 5x is a quadratic equation

2) x²+4=x²+x

=> x = 4 [ x² cancels out ] is not a quadratic equation

3) √x + 2 = 5x is not a quadratic equation

4) 3/x + x = x³

=> 3 + x² = x⁴ is not a quadratic equation

in a quadratic equation,. highest power of x has to be 2

standard form of a quadratic equation is

ax² + bx + c = 0

here b can be zero , c can be zero but a can never be zero
