Can this quadratic be solved by BOTH square root method AND factoring?

16x² - 25 = 0

• Yes!

• No - just square root method

• No - just factoring

Factor: x² + 24x + 144

• (x + 12)²

• (x + 9)²

• (x + 15)²

• (x + 13)²

Find the value of "c" that completes the square. Then factor the perfect square.

Factor: x² - 4x + 4

• (x + 2)²

• (x - 2)²

• (x + 4)²

• (x - 4)²
