Find the error in the following problem. x^2 + 2x - 80= (x+8)(x - 10)

• The 10 should be positive

• The AC Method must be used to factor it.

• The signs should be reversed for 8 and 10

• It's Prime-will not factor

Factor completely:
 3x² + 5x - 12

• (3x + 4)(x-3)
• (3x - 4)(x + 3)
• (3x + 3)(x -4)
• (3x - 3)(x + 4)
