How do simply polynomials?

Question

28w+12

a³b-3a²b

9m²-49

36x^5y³z-54xy²

etc

Answer 1

I will do the last one for you, since it appears to be the most complicated, and you try the others.

 

36x⁵y³z - 54xy² = ?

 

36 = 2²3²

54 = 2¹3³

Common factor is 2¹3² = 18

 

Common factor of x⁵y³z and xy² is xy²

 

36x⁵y³z - 54xy² = 18xy²(2x⁴yz - 3)
