B) xy-3x+y-3
C) x²-4y²
D)x²-10x+25
E) 2x²-3x+4xy-6y
F) 12X²-21x
G)9x²+6x+1
H) 36-p²

Answer 1

Bom dia Geovanna

a) 9x²y+15x²y  = 24x²y

b) xy-3x+y-3 = x*(y - 3) + y - 3 = (x + 1)*(y - 3)

c) x² - 4y² = (x - 2y)*(x + 2y)

d) x² - 10x + 25 = (x - 5)²
 
e) 2x² - 3x + 4xy - 6y = (2x - 3) (x + 2y)

f) 12x² - 21x = 3x*(4x - 7) 

g) 9x² + 6x + 1 = (3x + 1)² 

h) 36 - p² = (6 - p)*(6 + p)
