Answer 1

Answer:

1 and 2 are quadratic equations

Hope it helps you!!!!!!

Answer 2

Answer:

This is ur answer,

Step by step solution:

1)3x² - 5x + 3 = 0

- 2x + 3= 0

This is not a quadratic equation.

2) 9y ^2 + 5 = 0

it in not in the form of

ax + by + c = 0

It is not a quadractic equation.

3) m - 5m^2 + 4= 0-5m ^2 + m + 4 = 0

Yes, it is the quadractic equation.

4) (1 - 2 )( 1- 5) = 0

No it is not a quadratic equation.
