Question

z - 7/z = 4z+5 is quadratic equation or not

please it's urgent ​

Answer 1

Step-by-step explanation:

Yes, it is a quadratic equation.

By solving at last you will get 3z²+12z = 0.

Answer 2

Answer:

yes, it forms a quadratic equation

z-7/z=4z+5

cross multiplying left side we get,

(z^2-7)/z=4z+5

z^2-7=z(4z+5)

z^2-7=4z^2+5z

-7-5z=4z^2-z^2

3z^2+5z+7=0

Hence, this is a quadratic equation in z
