Default algebra 1 help.?

how whould i solve using the perfect squares method? if posible can you explain why?13. x^2 – 14x + 49A (-x – 7)(-x – 7)B (x + 7)(x – 7)C (x + 7)(x + 7)D--this one was incorrect---(x – 7)(x + 7)E (x – 7)(x – 7)F This polynomial cannot be factored by using the perfect squares method.16. 4x^4 – 20x^2 + 25A (2x^2 + 5)(2x^2 + 5)B (2x^2 – 5)(2x^2 + 5)---this one is not it. C (-2x^2 – 5)(-2x^2 – 5)D (2x^2 – 5)(2x^2 – 5)E (2x^2 – 5)(-2x^2 + 5)F This polynomial cannot be factored by using the perfect squares method.
