Question and answer
Select all of the following that are quadratic equations. 3 2 - 2 x = 2 x + 5 7 x2 + 5 x - 2 = 0 5 x - 1 = 2 x + 7 9 x - 2 = 0 6 x2+ 15 x = 0 x3 - 3 x2 + 1 = 0
The quadratic equations are: 3x^2 + 5x - 7 = 0, 5x^2+ 15x = 0, x^2 - 4x = 4x + 7.

Here are the quadratic equations from the list you provided:
3 2 - 2 x = 2 x + 5
7 x2 + 5 x - 2 = 0
6 x2+ 15 x = 0
The other equations are not quadratic equations because they do not have an x^2 term. A quadratic equation is an equation in the form of ax^2 + bx + c = 0, where a, b, and c are constants and a is not equal to 0.
