Answer 1

Are you familiar with the quadratic formula?

Answer 2

Kind of, I just don't really understand it.

Answer 3

type khan academy quadratic equation into google. your questions will be answered.

Answer 4

Here's the general form of a quadratic equation:
ax^2 + bx + c = 0
If you compare your first quadratic equation,
–7x² + 6x + 3 = 0,
you'll notice that it follows the same form. In your case, a = -7, b = 6, and c = 3.

Answer 5

The quadratic formula is a method of solving any quadratic equation of the form
ax^2 + bx + c = 0
All you do is you substitute the values of a, b, and c into the formula to get the solutions to the quadratic equation.
