Respuesta :

Sure! Here are the matches for each expression:

14. x²-25 = (x+5)(x-5)

15. x²-3x-10 = (x-5)(x+2)

16. x²-4x = x(x-4)

17. x²+x-20 = (x+5)(x-4)

18. r²-16 = (r+4)(r-4)

19. 3x-6 = 3(x-2)

20. x²-9 = (x+3)(x-3)

21. x² - 1 = (x+1)(x-1)

A. x(x - 1) (matches 21)

B. 3(x+1) (matches 19)

C. x + 5 (matches 17)

D. x+ 2 (matches 21)

E 12x (matches 16)

F. x+3 (matches 19)

G. x(x - 5) (matches 14)

H. 2(x+4) (matches 15)

J. x+3 (matches 19)

K. x-5 (matches 14)
