Question

Identify the GCF of 10x^4y^3 - 5x^3y^2 + 20x2y.

10x^2y

10x^3y

5x^2

5x^2y



Which shows 54^2 - 46^2 being evaluated using the difference of squares method?

54^2 - 46^2 = (2916 + 2116)(2916 - 2116) = 4,025,600

54^2 - 46^2 = (54 + 46)(54 - 46) = (100)(8) = 800

54^2 - 46^2 = 2916 - 2116 = 800

54^2 - 46^2 = (54 - 46)^2 = 8^2 = 64

Answer 1

5x^2y for the first one?
