Question

Check whether (4x-3)^2-16x^2+15=0 is a quadratic equation or not.

Answer 1

Answer:

No, it's not a quadratic equation.

Step-by-step explanation:

becoz when we open the bracket (4x-3)^2 it gives

16x^2 + 9 - 24x

on putting this in the given equation we get

16x^2 + 9 - 24x - 16x^2 + 15 = 0

here 16x^2 - 16x^2 becomes 0

and thus it does not forms a quadratic equation.
