Question

Can someone pls help me

Answer 1

U= 3x and V=2y^3

Explanation:

9x^2= (3x)^2

4y^6 = (2y^3)^2

=(3x)^2 - (2y^3)^2

Apply this rule below

x^2 - y^2 = (x + 7) - (x - y)

(3x)^2 - (2y^3)^2 = (3x + 2y^3) + (3x - 2y^3)

= (3x + 2y^3) (3x - 2y^3)

Answer 2

C

Explanation:

9x² - 4
`y^(6)`

can be factored as a difference of squares , that is

(U + V)(U - V)

9x² - 4
`y^(6)` = (3x)² - (2y³)²

with U = 2x and V = 2y³
