Question

Which equation is a quadratic equation?

3x − y = 8x + 2

y = 7x(5 − 2x) + 9

7x^2 + y = (3 + x)(7x − 1)

y − 3 = (x^2 − 3)(8x + 3)

Answer 1

wat do you mean by y=?

Answer 2

idk that was in the question

Answer 3

put y=0 then this is quadratic equation y = 7x(5 − 2x) + 9

Answer 4

For what equation when you will solve then you get \(x^2\)..
