Solution

It seems like you've listed a variety of quadratic equations and expressions. Would you like me to help solve any of them specifically? If you can clarify which ones you're focused on, I can walk you through the steps. Here's a brief rundown of some common types of equations in the list:

  1. x² = 4: This is a simple quadratic equation, and we can solve for xx.
  2. 7x² + 21 = 0: A quadratic equation where we can solve for xx by isolating x2x².
  3. x² - 8x = 0: A quadratic equation that can be factored.
  4. x² - 10x + 25 = 0: A perfect square trinomial.
  5. 2x² + 5x - 3 = 0: A standard quadratic equation that can be solved using factoring, the quadratic formula, or completing the square.
  6. x² - 3x = x + 30 - x²: A quadratic equation where we can combine like terms and solve for xx.
  7. 14x² - 14x - 14 = 2x² + x + 13: A more complicated equation that requires moving all terms to one side.

If any of these stand out to you, or if you want me to start solving one, just let me know!

Would you like me to solve the first one for you as an example?
